Routers are not overly expensive. Might want to get one (plug in 120v). It should have a removeable clear view of the cutter, a light, easy to control on off button, a good edge guide, and come in a bag with space for cutters.
As stated above, Carbide Only.
The straight ones are very important. Use to cut dado joints and rabbit joints. Or any grove. Dovetail joints are good also with a router. Get a few sizes up to 3/4" - Take several shallow passes when using bigger cuts. I like to make the last pass pulling the router to me, never pushing it away. And a router shouldn't exist without a Roman Ogee cutter for decorative edge cutting. Take it easy when ending the cut at both ends. Have fun. Also, get a broom or shop vac. But with all the other tools you have, I would guess that you already have a vac. Have Fun.
