I have been riding sleds my whole life its to bad you have a small budget. The type of sled you described would be a cross over. they have a little bit of a extended track for powder my buddy has a skidoo and it rips like a mother effer. i liked the cross over style so much I went out and bought a cross over for my self,mine is a Articat crossfire. its perfect for me. It can go down the trails with cofindence and also dish it out in powder. only problem i only got to ride it 6 time this past winter. we had almost no snow in michigan all winter.
