I am thinking about getting another quad, and would like a 4x4 that has a good fun factor as well as can be run in the snow and mud. What do you guys like? How do the prices run on them new/used?

 

Currently available, I'd say the Vinson Auto. In a few months you could have a new King Quad. I'm sure the new KQ is going to be the talk of the ATV town.
Eiger kicks butt, too. But it's 'merely' a 400, so some people aren't happy with the power. Kind of crazy considering 6 years ago 400ccs was pretty big.
