Here off the eastern short of Lake Ontario, in the Tug Hill region, we get snow, lots of it. Barnes Corners had over 300 inches last season, and locally where I live we had 220 inches plus. The Watertown NY dealer that sells Kubota and NH carries Smyth snow throwers, a well-make unit from Ontario. They start at $2100 new.
In March 2009 I found a used 3ph 48" Loftness in excellent condition. Loftness is a very well-regarded brand. I bought it for $1200 and had the dealer install a hydraulic motor for chute rotation. Loftness doesn't make 48" units any more (having dropped them last year). Their 60" are somewhere north of $4k new.
Some favor a front-mounted unit, and for Kubota they are usually more than $3300. I will work with this 3ph unit for now because I cannot afford the front-mounted one.
Maintenance is everything. If you find a used unit that has been reasonably cared for, you might be good to go.
