I'm exactly your size (ok, maybe 10lbs heavier) and I picked up a Jackson Super Star at the end of last season. I only got to paddle it once at Salida when the Ark had a wierd surge and it was pretty sweet...take some getting used to from my big easy but I think I'll like it. It's comfortable, which is huge when you have long inseam and big feet.
Whatever you end up picking up, pick it up used. In my opinion, new boats are not worth the price. If you wait just a couple weeks while you watch this site and bt you should be able to score.
I hope in the future Americans are thought of as a warlike, vicious people, because I bet a lot of high schools would pick "Americans" as their mascot. -Jack Handy
