Finally, although some of the creature comforts such as electric start and a goggle holder may come standard on the other sleds, they can always be added to the M 8000.
So at the end of the day, you may spend a little less on the M 8000, but you will likely end up at the same elevation on the mountain as the Mountain Cat and SnoPro. So the choice is yours. Spend it on your sled or save it for some of the other necessities of riding.
FYI: the M 8000 153 retails for $12,399.
