I've only had stuff from overseas delivered by Fedex and Regular Mail. Fedex is nice in that you can track the package, but they can eat you up with customs fees. If I have a choice, and I'm not in a hurry, I'll have stuff sent via the postal service (Royal Mail/USPS). I've never had a customs problem and most times they don't take more than a couple of weeks longer.

From they way everyone is talking, DHL is even worse.

I've gotten to the point that I will use US dealers when I can. That way I don't have to worry about currency fluctuations or customs fees; the dealer handles those hassles.
