By the way,

as long as the parts can fit into a suitecase there´s no problem with shipping, taxes and that kind of ****, es my employer has 3 factories in the states, to witch collegues or me are traveling in a somewhat frequent manner.

Larger parts I ship in containers thru a friend in San fransisco and then I haveto pay about 30 cent a buck for everything. So I dont pay to much in shipping and taxes, but in TIME. I really haveto plan in advance.
