I am eligible for an early upgrade through Verizon. I am looking at the DROID 2 and wondering if certified pre-owned is a wise way to go. A CPOed droid 2 is just $49 from Verizon, whereas a brand new droid 2 is $199. Huge difference. They say they will replace it free of charge for up to a year if it is defective or stops working- which is about how long I usually go before I upgrade. Any thoughts?
