I have been using the Craftsman version for over 2 1/2 years. No problems, except for the on/off switch. I eliminated the switch, and use a foot switch. Also tell him to scrap the hold down foot. Use the screw from that to replace the lower blade clamp screw. Much easier blade changes. Same size thread, but larger grip area. Leave off the cover below the table. Also much easier blade changing, and cleaning. And, on my flickr pics, I have a couple of pics of my own zero clearance insert. Works excellant for me. Replaces the plastic insert. Hope this helps!
