I second this, I've had nothing but great experiences dealing with them. I just ordered some stuff from GB for a winter project. They quoted 6,000 yen (less than $60) to ship two rims, a drop handlebar, and some small parts to California, versus 3500 yen to ship the same stuff minus the rims. Shipping last time I bought tires from them was <$20. Prices usually come out well below Compass etc even with shipping factored in.
