Hi, Me and my dad are looking into getting into snowmobiling and we were wondering what kind of a sled we should get. We need something reliable and capable of riding on trails and powder we are also looking for something a bit older since our budget is quite tight around 1990 to 2000 I have seen lots of summits 600's and 700's are they any good? We aren't looking for anything crazy powerful but enough that we can have some fun Any recommendations are greatly appreciated.
