I like those benchtop shapers - used to have a JD Wallace "Workace" and now use an old Delta light duty model. What all did your shaper come with - motor, stand, cutters, etc.? I think that one uses 1/2" shaper cutters. They're not hard to find if you don't have a good variety to choose from. Routers spin up a lot faster, and router bits are easier/cheaper to get. The shaper cutters, though, are pretty easy to resharpen when needed, and the machine runs a lot quieter than a router table (assuming you use an induction motor).
That shaper is a pretty simple machine and is a lot more robust than any router you'll ever use. Replacing the bearings should be pretty straight forward, and a decent notched belt will handle the small pulley just fine. I expect it will clean up really well.
Have fun with it.
