zr600, I have a BX1850 (little brother to your possible model) and I am almost unhealthily attached to this little machine. We have about 500 yards of driveway to clear, a decent sized garden to till, and 2 acres of actual lawn to mow, not to mention our forest trails that we keep mowed in the summer. Our machine is the perfect size for what we do, but a couple extra HP wouldn't have been a problem either. This is just the one that came up on a good deal at the time.
The only issue I had was with the LF tire having a bead leak, which a tube solved for only a few bucks.
If you can get one on a good deal, BUY IT!
