I've had both, the craftsmen and the harborfreight one at 10''. I feel the harborfreight one is just as good and for like 30 bucks cheaper (with 20% off coupon and sale) one can get the sliding 10'' saw.
just my .02
I have a lot of harborfreight tools and a lot of Craftsman tools, and I know I can get parts for Craftsman tools through Sears.
I consider the Harborfreight ones to be throwaway if they are out of warranty and go bad due to difficulty getting replacement or maintenance parts.
Maybe HF has improved their parts availability lately, but that was certainly true in the past.
