I have been satisfied with a Carniolan queen I bought from Glenn Apiaries in
California and a Midnite queen I got from York Bee Company in Georgia.  There
are many other sources for these bees.  If you have access to the world wide
web, Barry Birkey keeps a pretty complete list of bee breeders and queen
suppliers at http://www.birkey.com/BLB/Beekeeping/suplybe.html and the home
page for Glenn Apiaries is http://member.aol.com/queenb95/web/home.html
I'm sure there are a lot of other good (and bad) places to buy the queens you
want, but I have been happy with both the quality and the good services of
these two providers.  I also have All-Americans and Buckfast from Weavers in
Navasota, TX (http://www.ipt.com/bweaver/) and I have no fear of AHB in them.
Weavers claim to put their mating nukes in the center of huge bee yards that
basically saturate the area with EHB drones so there is almost no likelihood
of an AHB mating.  I don't know about AHB findings in that county, but Brazos
County currently has no confirmed AHB findings.  I wouldn't worry about
Weaver's queens.
