Difference between a table saw sled and this ... - Family Woodworking

Hi All

I got a flyer with Rockler advertising this gadget

http://www.rockler.com/gallery.cfm?O...Select=Details

and i was wondering is there any difference anyone can advise me between this and a normal table saw sled we would make for ourselves.

I dont get why one would want to have a have disc loose on the other side of the blade.

Maybe i am having a blond day but would seem to me to have a sled with or without a variable angle cut and have the sled go back and forth would be better than their arrangement.
