I'll pipe in for Chris here, he can't go and upgrade through T-Mobile as he is participating in a Best Buy discounted plan. Now that Best Buy no longer carries T-Mobile if he were to go and get it upgraded they would notice that he is on a plan that they should no longer honor. Hence his desire to get a phone through different means.

I have had good luck with the few phones I have gotten off of EBay, just pay attention to their feedback, and use a credit card, that way if you get punked on it you can go to your CC company and they will go to bat for you, only as a last resort though.
