I bought an 07 M8 last year brand new. I am a stock guy and not overly concerned with HP because, frankly, all of the stock sleds today go amazing places and I like the challenge.
I have had no problems with my M8 and it is an incredible kick to ride...it has some serious fun factor. My brother rides an 05 rev and while that is an awesome sled he has trouble doing the boondocking and sidehilling that my M8 will do.
Summary: if you aren't into only HP and want a fun sled to ride with a lot of finesse, then an M8 will work for you.
PS - I did ride the 09 M8 and M1000 and both were incredible.
