Well I just ran down to the local Yamaha shop and rode a '01 WR426. Oh, man that thing has scary amounts of power, just what the Dr. ordered!!!! Rode the 250 as well, and while I was impressed I believe it would bore me after a little while. Anyhow, just have to say that I can't wait to get one of these, just gotta get the TJ ('99 Wrangler) sold first.
