Nice. I'll check out the Extreme. In the cheaper category, Mine got some good reviews on Amazon.. My wife and I really like it so far, even with the less-than-fantastic stuff we have right now. Now I'm grinding up some old leaves and stems. Still seems to work okay. I like the grinder a lot. I'm embarrassed to admit I didn't know those existed. I've never been a joint roller.
I don't personally own one, but all my friends who do are in love with theirs. I have to say, that I am to, its much a cleaner high which I enjoy, and you can use the AVB for joints, bowls, etc. I have been shopping around on amazon a little for one and came across this one, definitely considering it, its cheap, and has some good reviews!
