A lot of frames are knocked together in the far east these days, they're still good quality and the XTC frames are well worth the money so don't be put off. I'd be wary of buying over the net though purely because you really should try before you buy. Hand built frames from reputable companies will cost you a lot more though.
I used to ride a Spooky frame built by a chap called Frank The Welder in a shed in New York, paid £675 for it but it really was a work of art. There's a pic in the Bike Pics thread somewhere.
