I saw one of these in person a couple weeks ago at Home Depot in Salt Lake. Was kind of beat up, and definitely a work rig, but I fell in love instantly. I'd love to get my hands on one of these 4x4's.
I remember seeing a pair of those snorunner's at a pawnshop about 8 years ago in Nebraska, was like $1500 for both. I thought they were interesting, but Nebraska never got enough snow to warrant me buying them. Now I wish I had!
The kid that let me ride it is my son's buddy, hes into it like $300. It was surprisingly fun although it sucked in too little snow and in drifts. If you couldn't float the drift you were sunk. It is really light though. This kid picked it up in a honda civic by pulling pins and breaking it down. Cool machines.
