First: I got confused, and I'm still confused, by what exactly the expensive ones offer that the less expensive ones don't.
Also... reading about them I'm getting pretty convinced that i should buy a cheapo to learn.. that's what they recommend. I'm thinking going expensive and then obliterating it in a crash may not be the wisest choice to start.
A big problem... a 'smart controller', by what I read, is the safest way to start... BUT... smart controller's cost mega-bucks. Catch-22.
Never the less... I'm guessing I pull the trigger any day now... even though I'm totally ignorant about them. - JamesJM
