Both work fine. I have a newer one and these are my old ones. Both show some wear on the cases.
Will trade for a pre-pay/pay as you go from someone like Virgin Mobile. I want a full keyboard.
8703e is in better shape, but older - $25
8330 has some wear on case/keys - $40
I think I have 1 extra AC charger to go with first buyer. Otherwise, they can be charged from your PC with a standard USB cable.
