After going through several gimmicky touchscreen phones, I recently reactivated my Motorola E815. Why? I remembered it was the BEST cell phone I've ever used. It had no business sitting in the drawer. I also bought an extended battery & oversized cover for it on ebay.
ebay. Plenty of e815 to be had. Cheap. Look at seller feedback rating, confirm clear ESN and physical and working condition of phone. $20 - $35 for a really nice e815. I know b/c I recently bought one to use as an extra battery charger and it turned out to be nice enough to activate the phone. My original e815 is now the battery charger. Best of luck.
