I must have been reading your mind. I just posted on the prop grease tube thread, and I was going to mention I always took off the Kaama props, because I haven't seen a set for years. The last set I saw for sale was for $2500, and that was at least five years ago. I don't know why someone would steal them, because as far as I know, they only fit a Kaama drive. You can buy adapters that you can put a bigger prop on with, but the adapters are $350 each, and it ain't like they give those props away either.
