My 20 year old Delta has broken in a strange way. The adjustment for the belt tracking has broken in a way that even Delta says that they can't find parts to fix it. I have been looking into the Grizzly sanders and have found two that I like. One is a refined version of the Delta. The other has a two inch belt and a six inch disk sander built in. It also has a half horse power! This is twice what the Delta has!
The two inch belts are a strange length at 27 inches. The good part is that several outfits carry this size belt. Grizzly can supply a 10 pack of belts in six different grits for $10! This machine bears some more research.
