Sounds like you'll be (ab)using whatever machine you get. JMHO, but for severe duty use, it all comes down to the hydro unit. Get one that's not designed for more than mowing the yard and you'll cook it in a few seasons.
I'd want one that's serviceable and preferably has a filter. Not sure which one that is; but any salesman worth his salt should be able to point you in the right direction.
