David Green's comments regarding skeps are important to consider.
Brushy Mountain Bee Farm (1-800-233-7929) offers two varieties, but does
not recommend keeping bees in them:
Cat # 752 is 15" high and sells for $22.95 plus 10# shipping
Cat # 593 is a set (one 8" and one 10") for $10.95 and 3# shipping
Their catalogue is full of great items and good information.
I am a novice beekeeper...
Best wishes,
David Rosenbaum
