bellweather - I bought a Hardy Lynx. It's a 52" cut, 25" height, 21" fan diameter. It has a very simple design, but seems pretty durable. This is the 3rd winter and I'm still very happy with it. A couple of modifications I made are some shoes to keep it from digging into soft ground and I put a turn-buckle on the chute deflector to provide more adjustment.
I had looked at Bradco, FarmKing, Buhler, Meteor, and Kubota brand blowers. Prices ranged from $2000 to $2500, after shipping. I went with the Hardy because my local equipment dealer carries them, making it the most convenient.
