While I understand about not taking time, I also think you could make a table top in less than 3 hours. Then buy a fence, or make your own. Order a stand or pick one up at Harbor Freight if one is near.
It takes me four hours or so to get to Rockler's store. If you make the top with two layers, 3/4 MDF on the bottom, 1/2 on the top layer, you can cut the exact size opening in the top for a plate, then an inch smaller for the bottom layer, pre-drill for screws up through the mdf and screw and glue the bottom to the top layer. Kreg makes leveling screws you can attach under the table at the edge of the mdf that will allow you to level the plate with the top. Rockler's table just uses blunt tipped screws up thorugh the bottom for leveling the plate.
I like Rockler's fence and have used it for years. It's about $120. I have the Rockler metal table support, already mentioned, actually two, one for the router, the other for the sliding miter saw.
Can't see any way to keep the cost much below $300 buying commercial and getting all of what you want, and more depending on what brand and model you choose. The bench top tables are just too small for general use, at least for me, especially when routing a longer piece that's much longer than the table itself. Its really easy to have the supported end flip up and ruin your cut.
If you still choose to buy, I suggest you up your budget to get a nice, full size setup. You'll be using it for many years. I'm sure there are many other brands, but I can only speak for the Rockler setup.
The more I do, the less I accomplish.
