Help me choose a tool.

Ok, here's the scenario. I need a detail sander. Something that can get in nooks and crannies. If yall remember a ways back I asked to design a shape.

In typical mndsm fashion, I got a little ways into that project and promptly forgot about it for like a month. And then I picked up another project. And then my house got struck by lightning. And now I'm finally settled with that...sort of (still waiting on Duke, but I replaced the last Xbox last week so we're technically whole at this point) I'm circling back to this. And while i'm finding my palm sander will do the heavy lifting, there are certain areas within the shape that I can't get into due to the size of said palm sander. ENTER- detail sander. I initially thought about just grabbing a mouse palm sander, but that seemed a little too single use, given that I already have one palm sander I only use for one thing. In random googling I came across

This. This is pretty cool, right? Neat little detail sander. HOWEVER, I was trying to find something that was A- not Ryobi (We'll get into that later) and B cordless? ( again, later) and I started down the path of an oscillating multi-tool.

This critter right here seems about right. It does all the things, has a sander, probably some other stuff, and in the case of THAT particular model, is the baddest one Bosch makes. I like that. 

Now for the question. HOW do I approach this? The one above is the most expensive option on my list. It's also the most...cost effective in a way, because it's the baddest, comes with the most E36 M3, is the most powerful, has the fattest discount (being a CPO tool...which is questionable a bit but whatever). 

https://www.lowes.com/pd/Bosch-3-Piece-Brushless-18-volt-Variable-Speed-Oscillating-Multi-Tool-Kit-with-Soft-Case-1-Battery-Included/5014281329?cm_mmc=shp-_-c-_-prd-_-tol-_-ggl-_-PMAX_TOL_000_Priority_Item-_-5014281329-_-local-_-0-_-0&gad_source=1&gclid=CjwKCAjwhvi0BhA4EiwAX25uj6DFfDHzhdKGhtgvowq8T3uIABNv4D2Us2Xy4klxLbA0GDyV5HZDJRoCPDIQAvD_BwE&gclsrc=aw.ds

Next on the price is right- the bosch cordless. Advantages- it's a brushless, cordless 18v. It fits right in my ecosystem. I have tools that have these batteries already. This one actually comes with MORE battery and charger. This is all good. It's at Lowes. Lowes will drop that pig on my doorstep today if I pay the man. DISADVANTAGES- it comes with no other stuff. No sanding gizmos, no blades, no nothing. Attachments could easily make it as expensive if not more than the first one. 

Down the ladder from there? 

Choose your hammer store adventure. It's florida. I have them all. IF I CHOOSE THE HAMMER STORE VARIANT (northern, tool outlet xxx/whatever, HF) it will be corded. I am not interested in starting or maintaining a second/third battery system. E36 M3's annoying. I do not have a problem with cords, I have enough extension cord to go around. and around. ADVANTAGES OF THE HAMMER STORE- it's cheap. It's the hammer store. It might come with stuff? I'm not entirely sure how much I plan on using this tool so it might be a wiser decision to not sink $$$ into this  adventure. DISAVANTAGES OF THE HAMMER STORE- it's the hammer store. I may well end up with a hammer. I've heard tell they're obnoxiously difficult to work with when it comes to swapping heads. I'm mildly concerned with overall quality of the tool and ability of it not to tear my E36 M3 up. 

Somewhere in between all of that there are various non-hammer store value brands- ryobi, kobalt, whatever else- I haven't really looked too much into those, I figure if I'm going value I'm going VALUE. Kinda wish they just made tools, painted them yellow and it said TOOL on the side of it like some generic chips. I'd buy that one. 

I just brought home a Ryobi cordless oscillating multi tool, two batteries, and a charger for about a hundred bucks and I'm quite pleased with it.  They run pretty good sales at the store o' Orange and the ecosystem is friggin' huge.  I know it's not the most amazingist quality evar, but for around the house use, it's going to be quite fine and provide me with a good stepping stone out of my current batteries (old, old, old, old Craftsman 19.2v C3 lithiums) and into something newer.

In your shoes, though, the cordless Bosch makes the most sense to me unless you're looking to change or add batteries.  The tool is something you'll find yourself reaching fairly frequently so unless you're trying to switch to a new battery anyway, I'd bite the bullet and get the one that matches what you already have.  That is kind of crappy that they don't include any blades or sanding pads at all.  I'd especially get that one if you can find the $99 deal with the battery and charger.  It shows "out of stock" for me, but I'd think the extra battery and charger would be worth most of that hundo.  The bare tool for $160 seems to be the other option I see and that seems like less of a good deal, especially after you add the attachments that the cheap bastards should be including in the first place.

I bought a cheap, corded Worx brand unit when I was "Oscillating multi-tool curious" thinking if I liked it and used it enough, I would upgrade to one that used whatever battery system I had. 

6 years later I still have the Worx. Never felt the need to upgrade, nor use it enough to justify spending more money.  My main uses for it are trimming baseboard molding and scraping undercoating. 

I bought a corded Ryobi angle grinder years ago and it's still kicking ass, works great. Small sample size, and I'm a home user, but I wouldn't rule them out. 

My stepfather bought a bunch of their cordless tools a year ago and has been happy with them. At least around the house, they seem good enough. 

The nice thing about the Bosch oscillating tool is that by using a grinder, you can shape an extra blade into any shape sanding pad you need to reach into any crevice and use double sided tape to attach the sandpaper.

I have the M18 one, get whatever brand cordless ecosystem you are in.  They all use the same consumables and do basically the same thing.  

I would use mine a lot less if I had to schlep a cord everywhere.

I only used Ryobi as an example. The long and short of it is, if I'm not buying a Bosch unit (I like the company ethics and how they're not secretly owned buy a mega-corp) I'll buy the cheapest hammer I can. I'm a hypocrite like that. Ryobi tools themselves have always performed fine any time I've used them.
