If you enjoy snowmobiling with the family I would recommend finding on of these, got one this fall and was able to get my wife back into sledding.  She never wanted to ride after having kids because we didn't want to leave them home to go have fun, and I didn't want to ride with a passenger.  We have had four kids in there for a 60 mile ride, it's so comfortable that my daughter falls asleep every time she rides.  Even rode in it myself.... for about 30 seconds.
