I'm no better than the next man (or woman) I want me a custom.
But the one nagging question, once you've dropped $2000 or whatever and waited a few months or a few years, you're not going to turn around and admit it wasn't worth it are you? Its a pretty common psychological effect, you make an investment and unless its absolutely clear its a dud you'll defend it. Stay true to your school or whatever. Why own up to a bad decision when you can just ride with the illusion..
So yeah, if there are any custom builders out there who want to prove me wrong, I'll happily do a double blind on some frame built for me...
