riding mowers / walk behinds

[skinnies]

A couple of buddies and I started a lawn service late last fall. Say Aug time frame. We made enough rev. to purchase a couple of gravley walk behinds. They needed some work, but the deal was to good to pass. I picked them both up for $1000. My thing is its time to update. What should we look at? We are looking at Bob-Cat, Bunton, and Encore. Are these good machines or do we look for something else. We are primarly taking on buisness, Ford's, G.M. accounts of that size. approx. 5-10 acers per account. We are in for the long haul, and we would rather spend the cash for a reliable machine.
thanks,
