$900 for bdx light drive, $70 for 09 helix( get a 40/36 slp). $550 powerclaw, around $400 for rear tunnel design, $100 ish 2 wheel kit. don't forget the rails are lighter to and the resale is way better. the 09 is a far better sled and worth 2k anyday. the mapping is better and the clutching had less problems( The clutching is the same but the sled is 22lbs lighter and the lighter track seems to make the belt and clutches work better. and yes a 09 will beat a full piped 07 except in a drag race, mainly because of the track but everything on the 09 will get you farther in the snow. If you are on a budget and plane on keeping the sled the 08 is still a great sled, but I'd take a 09 m8 over a 08 m1000 stock to stock. I think the only reason to have an m1000 is because of there potential with mods. if you go with it at least get the dealer to throw a PC on it.
