Al's suggestion is very good. I bought a Oneway banjo not long ago as a second banjo for a 32-inch tool rest and now use that as the day-to-day choice. Reasonable price, prompt delivery, and they do of course make banjos for 24-inch lathes. It is narrower than Powermatic so you have to be careful when it wants to drop in the Powermatic's wider bed gap when you move it around.
