An old Toro... and I mean
old! I think it was approximately 20" and 5 hp. When I got the Ariens 824, I set it at the curb for $100. The single-stage Toro actually did great in dry snow, but was too frustrating in the wet snow we so often get. The two-stage Ariens throws everything but the salted plow slush at the end of the driveway, as does the Woods... but the Woods has a 25 hp diesel behind it.
Well, actually, I did own one other single stage unit, which I forgot about! A 42" blower mounted on the front of my 1963 - 1965 IH Cub Cadet 123. Unfortunately, we did not get much snow in the few years I owned it, so I can't report how well it worked. The guy I bought it from seemed to think it really kicked ass, though.
edit: I just found a photo of my old Toro single stage! Toro SnowHound 20:
