Either way, make sure you get someone to check out the internal parts. Like it was said, those are what really matters, when it comes down to the line, and you wouldn't want your new toy to end up needing 200$ in repairs right off the bat, if you're runing on a budget. It may have a metal body, or it may have a plastic body, but where it matters is the quality and durability of the internal mechanisms.
I knew a man once who said "Death smiles at us all. All a man can do is smile back."
