Am in the market for a chipper shredder-8 to 10 hp to use on a heavily wooded 4 acre lot. I've done some research on a Bearcat 8hp(70080), the DR 10hp and the Craftsman 8.5hp. The Bearcat chips and shreds whereas the DR is used only for chipping(it is also $300 cheaper)-the Sears is 1/2 the price of the other two. Any other brands to research? Experience with any of these chippers? Thanks
