Opinions will vary, but I've always owned Ariens Snowblowers with great success. I bought my first Ariens 15 years ago. Never had any issues, only regular maintenance. I just gave that one to my brother and I bought another one. I live in Central Connecticut and get 80 plus inches of snow a year on the average. Currently, I use an Ariens Professional series to do my 200' long driveway, but I would imagine that the Ariens Compact series would be sufficient for an 800 sq. ft driveway.
