Prices of used Droids have actually gone back up a little. They dropped like a rock when the DI came out. I saw them as low as $150 mint with a clean ESN. They are hovering back up at the $250-$300 mark right now. Dunno if that will change when the X goes up for pre-order or not.
I sold mine for the Incredible....If i had it to do over i would have kept my Moto til i tried the incredible for a few days....I no everyone loves their Motos and it is very hard to replace ....i want mine BACK!!! just my advice.
