After a lot of fretting I just rec'd. the Kreg table system. It has a twist in rings. I think I'm going to like the fence system. It's a little less expensive than the others, but I'm hoping that Charles Neal's endorsement was more than just a paid appearance. I also got the casters, separate ON/OFF switch and micro-adjuster. I like the ability to adjust the height of the table. Just assembled it and have yet to actually use it, but I'm sure it will be fine. Using Bosch 1617 router which I can adjust from the top thru a hole in the plate with a hex key. In general I have always liked Kreg products, so am hoping this will follow suit.
