I don't understand what the problem is with shipping parts from the States? Yes, you do have to pay VAT and sometimes duty on the DECLARED value. Even shops will often work with you on this. However even if you pay the full amount with the lower price level, weak dollar and wider variety of products, it is often still cheaper than buying in Europe (look at Garmin GPS for example
If you stick to USPS Air Mail, the shipping cost is very good for items that are not too heavy and the stuff generally arrives in about a week (max. for me was 3 weeks once). So if you don't need something urgently and can't find it in Europe do not shy away from buying stuff in the States.
Heck, I should know, I am building a US kit car in Austria and have it shipped here in pieces!
