Kirk,

Mine is on order and will be here by the end of the month. I spent a lot of time on the forums and got feed back from a few that had the slider attachment. All who responded to my queries stated that it was easy to install, stayed square, and the fence was easy to remove and replace when ripping large panels was required. The only negative was that the
"legs" that stick out the side of the saw could be a trip hazard.

If you would like, I can contact you once mine is installed and I'll let you know if I think it would handle a very heavy table top.

Jay
