The American kit manufacturers haven't learned the secret. The more one pays 
for an item, the harder one will defend it and overlook it's deficiencies. 
We had an abundance of American cottage industry kits manufacturers AND 
designers, we drove them out of business with the plane of the week 
mentality.
