Ah..., Curmudgeon, hate t'tell ya but you are living up to your name...
You guys [ 'specially Ranger 50 ] pretty much have it covered. It's still pretty much a two horse race, and honestly ReyRey Era is the better package for way less $'s.
One thing which, well it should be more minor than it is: Personally I find a mix of numbers and letters easier to remember.
With it all in numbers I find myself more prone to being thrown off path.
I have to recall a tag #, a Partial Vin, a tech number, an ERA menu number, as I pull my knees under the desk...and it all goes blank. :(
Now, granted, I am getting older and dealing with more stress in my life but it just seemed easier hitting PRO and a number, than to hit a number, then a number.
Way easier, oddly.
But having waited half hour-ish daily through a tough patch for tech support to finally pick up the phone at ADP, ReyReys tech support is utterly amazing.
Such well spoken, sincere people, generally picking up first ring. No one knows all the answers, but they try hard, call back super promptly.
ADP's Websuite and I assume anything newer are the perfect example of software bloat, and glitz over foundation.
Oh and 6910 is ERA is really cool for control freaks like me.
ADP's attempt to copy it (code is on the tip of my tongue) was seriously weak.
