@sgcz75b - Steve - curious about your router table top. Can you tell me more about it: was it from a prefab table, and if not, I'd like to know more about your replaceable rings, and how you made the opening for them. I've got a Kreg plate with changeable rings so I know how they work, but yours is interesting.
It's made by Veritas. 16x24" 3/16th steel plate - will never sag. Clamping system underneath allows you to quickly remove the router, then replace to the same position without removing router base plate. Works with nearly any router, including plunge routers. A variety of inserts, ranging from 1/2 " to 1.75 " and an insert with guide bushings.
Great fence and also a right-angle sled for dovetails and other work. Came with work hold-downs, stops, and a few other goodies.
I bought it used for $250, spent about $75 on inserts and bushings. Using 2x8s for support and they fit perfectly without any work and allows me to easily change bits and adjust vertical travel.
It sits on an old B&D workmate. I also bought a foot pedal off-on switch.
I'm very pleased with the results. While 16x24" isn't big by some standards, so far I've not found limitations with what I need to do.
It's solid as Gibraltar.

The fence, right-angle sled, and a few other items are no longer available. My guess is that it was originally an expensive system to get into so sales were slow. When it first appeared 12-15 years ago it would have cost about 5-600 bucks to get it all, when other router tables were 2-300.
I wasn't familiar with the system until I saw it on Craigslist, did some quick research, and was happy to get table, fence, sled, hold-down, fence stops, for $250.00.
