Hi. There are a number of recent threads on router tables. You could spend quite a while reading about it. I bought mine, a Ryobi entry-level table that satisfies most of my routing needs at present. Perhaps I'll build the next one, when I decide what I need in a table that I don't already have.
I'm not slow, I'm pacing myself!

Usual kit: Table saw, band saw, dual base router and table, lathe, various saws, planer, sanders, and a multitude of hand tools.
