Just bought a Touch Pro 2...listed as "NIB" and "clean ESN" so there shouldn't be any problems there. Picked it up for $350 whereas through Sprint, w/out an upgrade, I would have been looking at $600
. Then went ahead and bought accessories for it (spare "OEM" battery, desktop cradle, and screen protectors).
I'm pretty leery as well, when it comes to electronics. I do know that I will steer clear and fork out the extra money (for the real deal) if the equivalents on eBay look like cheap crap.
