I've done kitchens in my last two houses. The first one was a nice update, the second was a transformation. Both were complete teardowns of all the cabinets, the second one also involved pulling a little stub wall. Did it all myself and don't regret it one bit. You spend more time in the kitchen than just about any other room in the house, especially if it's an open plan like ours have been.
Get thee to IKEA.
I liked their previous generation of cabinets better than their current ones, but they're still a killer value for the money. Their online design tool will make sure you have an accurate bill of materials and makes it much easier to plan. Some of the IKEA doors are solid wood, some are not - spend some time looking at what's out there. Their hardware (hinges and sliders) is awesome. Some people rag on IKEA because, well, it's not hand-hewn lumber or something but they're far more substantial than the 30-year-old cabinets I've yanked out of a couple of houses.
If you go IKEA, you can also build and install the cabinets yourself. It's a fairly quick process and you will save bulk dollars here. Then have someone else install the countertops. I recommend using wood glue along with the IKEA fasteners, it makes for a stronger box.
We went with a mix of drawers and cabinets for the base on our old one. On our new one, it's all drawers. A 36" wide drawer on heavy duty slides with a light is a really nice thing. On that note, soft-close and interior lighting is wonderful.
You can get butcher block slabs for countertops. The IKEA ones have changed, I'd probably go with the Home Depot options now. But it's a lot less expensive and easier to DIY than quartz. We have quartz in the new one, the last one was a mix.
Online is definitely the choice for fans. They all seem to come from Broan, but the better ones are a lot better than the cheap ones. Pay attention to sound ratings.
If you put a power outlet inside a cabinet, you can rig up a drawer with a multi-outlet USB power supply. Then you add chargers for all of your devices and now they have a place to live and charge where they're out of sight.
No pics of my redos at the moment, but I can supply them if desired.
