Hello Armadillo,
Yes, we try to stop by the forums as often as we can to check in, see what's being talked about, and offer our 2 cents. But questions won't always be answered directly by us in less than 24 hours, particularly when there are magazine deadlines swiftly approaching. 
We do try though. Katie actually alerted me to your question yesterday, but I didn't have enough time to respond properly until today.
In our workroom here we use a Sierra Evenheat E360. It has an interior that measures 8"W x 6"H x8"D, which is just large enough for a bronze clay firing container and some short kiln stilts. If you're planning on doing much with bbronze clay, I'd suggest you get a kiln that size or larger (they make them with interiors of around 12" square). Since they're not exactly cheap, you don't want to have to upgrade to a larger size shortly down the road.
The other key is that the kiln must be programmable. The firing schedule for bronze clay is very specific, and it takes a long while to complete. I can't imagine baby-sitting a manula kiln for all that time! 
Best of luck with your kiln shopping. And have fun experimenting with that bronze clay!
