I've read about the DE hives, and they sound very interesting. Lots of interesting ideas, and all reports seem to be positive. At the same time, I've captured swarms in cardboard boxes, and kept them there (with some brood comb) for a month. I'm not so sure the bees are as particular as we seem to be. You find them in cracks in large rocks, holes in trees, old tires, and occasionally, building comb in the open. I'm a firm believer in standard sizes as a matter of economy, and management. I'd like to try them, but they are a little pricey. Guess I'll have the winter to mull it over. 37 degrees and snow down to 5200 feet this morning. Summers over and fall is fading fast.
