You can mount most routers under a table. Your table can be as simple as a piece of plywood or MDF. You will need a homemade fence also unless you have bearings on all your router bits. Woodworking supply houses sell some very nice tables. $$$
I prefer a heavier table to a small little sheet metal bench top router table. But that's just my opinion. The small bench top router tables are available at Sears, Home Depot and Lowes. Some are even made of hard plastic. If you want to start cheap and see if you like it, maybe that's the way to go. Good luck to you.
If you don't have time to do it right the first time, when will you have time to do it over?
