Any recommendations oin a snow blower? I live in Maryland, so we don't get a lot of snow, but a few times a year we'll get between 6-24 inches. My problem is that I have a lot of area to clean (inclined driveway, long wlakway to the house and sidewalks). I'm thinking something smaller. I was considering an Arien -- maybe a 5 hp model -- but the only place that sells them around here is Home Depot. Any thoughts or suggestions are appreciated as this will be my first snowblower.

Also is there a big difference in performance between a 5hp and a 7 hp unit?
