Jim Wood's original stove is the Cat Stove. The Super Cat is a winter version. He has them on his website (assuming it's still up, I haven't looked in a while). Jason Klass has some stoves on his site too, I think.

There must be hundreds of videos on YouTube of stove tests, stove making and all that, so you can spend hours (assuming you avoid the millions of dancing cats, cute puppies and bad music videos) comparing the different designs.
