Snow Removal

I have a lake cabin in Minnesota that I am trying to figure out snow removal for. The drive way is long, about 350ft and is gravel. Over the 350 ft, it rises about 20 ft, so there is a bit of a grade there. It is also a narrow driveway, so a blade is not an option, I need a snow blower. I talked to my local John Deere dealer and have narrowed my choices down to two, the X739 with four wheel drive and the X584 with four wheel steering. The X739 is about $8500 more expensive but I get four wheel drive. Do you think it is worth it? Any advise is welcome!
