They don't bother me. The American ones are cool simply because they were made in America, they're a little older, and probably more care went in to the welds? I always wonder why is it that just because a guy lives in Japan or Taiwan and is a welder, why do we assume he has less pride in his work that we do here? I don't know, the proof is in the product I guess. I've seen some un-even standing platforms, nothing really too much worse than that. I've seen some pretty crappy welds I suppose, not necessarily all on Hutch's, but I don't think they all came from overseas.
Example of some craziness, an old WAL frame of mine:


The rest of it's OK, but those rear dropouts look terrible.
Anyway, I made a replica of my childhood Trick Star out of a baseball frame, and I'm totally happy with it.

My original one back in the 80's was an American one, and if I ever come across another I may swap it out just for the fact that that is what mine was and it would be a little more accurate, but if I never come across another, I'm totally happy with this.
