Sandy:

I have bought Arca-Swiss from Robert White, and from Badger Graphics. I can enthusiastically recommend both dealers. I had no shipping hassles from RW. There aren't likely to be problems with cameras, but I have gotten good support from Badger and Robert White, as well as from Arca-Swiss in Besancon, France. I just picked up the phone and called them and they were spectacularly helpful in answering my quesions.
