I used a Craftsman 78 (made by Stanley) just a few days ago to make a replacement drawer slide out of a piece of scrap teak. So much more enjoyable than setting up a router table and making a lot of noise and dust. It helps to scribe a line with a marking gauge to get a clean cut on the first few passes.
If you do find a used one, make sure that it has the rod and fence as well as the depth stop (not shown above because if is on the opposite side). Not very useful without the fence and rod but you can work without the depth stop.
