I've used (and still have) the JIG IT® Shelving Jig w/Self-Centering Bit and find it's nice for using on boxes that are already made. Tear out is an issue with the drill bit.
I have used the veratis jig as well. It was a PITA to set up. It's now down the road.
My main rig is the bosch FSN OFA with a bosch holy rail and router. My favorite so far.
I have no experience with the LR32 system but I can assume it's a nice system to use based on my experience with a holy rail and a router.
Took a look at the Bosch, I guess in Bosch's case copying is the sincerest from of envy. It is good to see others following Festools system approach. I've been using the LR32 for about 8 years now and find it a very easy system to like. For small jobs the LV jig works fine with the proper drill bits.
