I was looking at them about the time they stopped making them. There was dealer in Anchorage and he said they cost about $35,000 including shipping. They came with a small 4cyl Ford Industrial (53 hp) and the biggest performance issue was they were slow. With all the grooming attachments they are heavy but they are designed to stay on a groomed/packed trail and did pretty good at that. The grousers were not real tall but maybe like an Imp.
The dealer said they were getting ready to put a Saab diesel in the next generation but the deal fell through and that was when they stopped manufacturing them. There was one at the local High School that I used to drool over and it seemed like a well built machine for grooming.
