Dadant out of Paris, Texas, Bill @ Honeymoon apiaries, Goldenbee, Brushymountain, and Betterbee, and Walter T. Kelly. Locally, The Busby's out of Varnado, Louisiana for Russian bees. I've purchased beevacs from Southwestern bee supply (pricey) and just recently purchased a beevac from Kelly, although someone else makes it, it was a good buy, 1/2 the cost of the Southwestern one and more compact.
