Seem like a good deal? I'd prefer to look at the bike myself and see if it's really in mint condition...
The guy also seems to be a non-paying bidder, which leads me to believe he might not be a good seller.
If I lose the auction for my fork tomorrow, maybe I'll bid on that if no one thinks it's a bad idea. I've been wanting a BMX bike, and expecting to pay about $300 for one, but a cheap used one that cost about that much(Did it?) sounds good too.
