Not to discourage you, but aren't they going for $100 new at the stores now, with the S4 coming out soon ....
It should sell, but maybe slightly lower (just check the going Ebay prices).
I do agree with Rey, it would be worth it for one that does not want a new contract.
So, if you buy Used, theres no Contract ?
I didn't know that ...
I thought when you activated it, it would kick in a contract ....
