I am not sure what your price range is, but I purchased a woodmaster W-2675 at the recommendation of a furniture making friend of mine. This machine has been running in my shop since 2004 with no problems. It has a 24" fixed drum with adjustable height infeed table. much more affordable than a belt style thickness sander, although it's a bit slower. I find that it is perfect for lutherie. I could not be happier with this machine. Made in the US.
