You may also check with BBQ Bubba. He may be willing to ship overseas. Then again, maybe not :)
If all else fails, as Larry said, you'll probably find more than a few Brothers willing to help out, myself included.
As far as what I use, it's hard to go wrong with Plowboy's Yardbird and Bovine Bold or Spicewine's Hen and Hog Dust and Heffer Dust. Spicewine's All Purpose Seasoning is good stuff as well. Great Lakes BBQ Supply carries all of these.
