used PS3 CFW buying advice
I'm considering buying locally through craigslist and then returning my cech-3001a (which makes me cry because it is in mint condition and I got it for around $170) to the pawn shop I purchased from. When buying a PS3 Slim 3.55 CFW, what should I look out for? how difficult is it to go back to OFW from CFW (and then back again)? finally, are there any obvious tests to weed out any hardware issues (opened console, bad BD, repaired YLOD, etc) that wouldn't be too ackward for the other person?
Thank you so much guys, long time lurker but it's my first post. I'm excited to get into the world of PS3 homebrew but a touch upset at sony for making a bad first step.
