I have the Delta jig. I love it.

A good fense makes everything sooooo much easier, better, more enjoyable, etc... After installing one, I was immediately pissed at myself for not doing it sooner. If you're wondering, the fence I went with was an Incra. I liked it so much, I did the same to my router table. The fence is just freaking cool. Kind of a PITA for space though. The T-bar sticks out quite a bit.
