I need a snow blower and am thinking about buying new. I live in Maine and get a lot of snow. I was looking at the deluxe 30 EFI, the Deluxe 30, or the platinum 30 SHO. Also not opposed to the Deluxe 28 SHO. I will be doing My driveway the size of 6 parking spots wide by 30' long so will be built up by the plow and then I also do a decent area in my back yard for a dog run. Appreciate any insight!
