I've heard of a guy on Woodcentral that added a Dewalt slider to his Unisaw and now I've heard of a another adding the Dewalt slider to his Grizzly 1023. Is this slider really that good?

I know this slider takes up a lot less room than the Excaliper, Exactor (spelling) or others but I'd be interested in hearing from anyone who owns the slider installed on a Dewalt or any of the other saws. That is, is the slider itself worth the coins?

Cheers
