That does suck man....That's the reason I never buy anything off of e-bay...You never really know what your getting until you actually receive it.

Actually, fixing it shouldn't be a problem. I would just drill 2 small holes, maybe 1/4" holes, on each side of the neck (at the biggest section of wood) and on the headstock to where the holes line up, and glue in a wooden peg for strength, and of course add glue to the entire joint being glued. Headstocks have been glued back on with success (not by me, never actually had to), so fixing the neck is a possibility. You'll just have to be careful to be sure the holes that are drilled match up perfectly....
