That is a great price if it is in great shape. Does it have the older 25hp Kolher command or the newer 27hp. The older 25 hp motors frequently launched the magnets from inside the flywheel usually causing costly (3-4 hundred) damage.
other than that they are good machines if you are chipping small stuff. Let me clarify I too cut alot of fire wood but for home heating so I dont chip anything I can burn.
The thing I find less than desirable is the feed shute narrows down to 6"X6" and when you send a bunch of pine branches or a fork limb in it doesn't always go willingly like it would in say a bigger machine or a bandit 6" machine which has a shute that only narrows down to 6"X10". Same max limb size capacity but better feeding. I found rather than lean into the shute and wrestle with this, also an unsafe practice, I keep a small saw handy and just partially cut the fork on one side before feeding and problem solved. By partially cutting you don't make more pieces to feed like you would if you cut all the way through. After running the machine a while you will have a good feel for the few forks that need a little cut to help.
Hope that was helpful
