If you don't want to spend 2 grand on a "pro" model then you just made your choice. Toro.
Dollar for Dollar the PowerMax 2 stage machines out-gun anything in their price range.
I like this one for ya, I'd prefer a model with the freewheel steering but that kicks the price up more.

Also look/ask about last year's models. With winter being a no-show for 2011-12, I know a lot of local dealers here have a ton of leftover machines that I'm sure they either paid for out of pocket (ouch!) or have been paying interest on the floor-plan financing. That means they are probably
desperate to unload them.

I'd be looking for a PowerMax 826OXE with freewheel steering and the Briggs OHV 8 HP engine.
