I think Polaris makes the best sleds. New/used depends on you. The value will drop quite a bit the first few years. If you can afford to get a new one, I would. Also, it is a good idea to buy where you ride. If you need service, it won't be at home. You will get taken care of much better for short notice, last minute problems if you bought the sled there. I personally wouldn't want to ride without studs - this is something to look into when you are getting ready to buy. If you will be on the lake riding, stop into
HK Powersports which is across the street from the Burger King on Paugus Bay. Go in and look around and ask questions. You can learn a lot that way.
