Local CL has an 8 HP chipper for sale...$250. Appears to be an older model but owner recently says bearings have been replaced and blades sharpened, says it will take up to a 3" branch. I know next to nothing about Troy Bilt or chippers in general...would this seem to be a decent deal if all is as stated? Something that will chip up to 3" is all I need since anything larger than that I would burn anyways!
