I'm not a 4-stroke fan, when it comes to sleds anyway. If I was looking for a utility sled, I would choose a Ski-doo model (Tundra, Skandic, or Expedition) with a 600 E-Tec engine. They are easy to pull-start, so I'm not worried about the electric start/battery not working when it's butt-cold. From what I'm told, the 600 E-Tec gets great mileage, and they seem to last forever.
