A long time ago I too struggled with the router table choices; and made one error of the “buy a cheap 'un” kind. Inevitable it was cheap & nasty. Eventually I got a Veritas router table with various extra bits. Sadly, they no longer make & sell it.
The big problem with router tables is that the table top needs to be ultra-stiff to resist the weight of the router strapped underneath trying (and often succeeding) to make it sag. ANy sag means horrible results in the routed parts. Virtually all those router tables made of anything other than metal end up sagging. MDF and similar stuff, no matter how thick, is susceptible to sag if the humidity in which it lives goes up even for a relatively short time. And over time, the heavy router will sag it too.
Thicker table tops also mean the router struggles to push some bits up above the table enough. The Veritas has a 6mm thick steel sheet as it’s table top. In the twenty years I’ve had it, with a Triton 3HP router strapped underneath, it’s shown zero sag other than the designed-in sag - a tiny amount compensated for by the unweighted table having a teeny crown, so it’s flat with the router attached.
It’s not easy to make such a thing yourself unless you’re a metal worker. Even then …
There’s also a need for a very accurately-made fence; and zero-clearance inserts of different hole diameters for different bits, in the tabletop. And …
In the end, a commercially made table is the only path to good performance and accuracy. Those able to achieve good performance and accuracy are never cheap. Even some expensive ones still suffer from the sag.
Not much use, this, I know.
