To answer the original questing as stated, my wife recently got a very basic Troy-Bilt Storm 2410 to do the walks and our large wrap around low deck.

It is a 24" two stage with elect start and that is about it. Small enough so that she can handle it and it appears that it will do the job. Probably could handle a small short drive way. Will have to wait and see how the Troy-Bilt Chinese engine holds up. She did really like it in the 1st small storm.
OK this is just a BTW talking about snow blowers. Towards the other extreme I do the 600' steep driveway and have used a plow truck for many years. Not a typical homeowners situation. As I already have a JD 3320 tractor, I picked up a 64" Frontier PTO snowblower this fall. Waiting for a real storm to see if it can replace the plow truck.
