Dude, I am not trying to bust your ballz on this, but a tiny bit of research would have gone a long way into saving you some money. I would consider this an expensive mistake, but everyone's wallet is different.

Anyway, you should be able to get 1/2 of what you paid, selling it on eBay. Perhaps more. I'd say post it with a starting bid of $50 and a reserve of 1/2 the original cost (or 1/2 of what you put into it).
