Hello Mike, I have one, one of the first things I wanted to do with it was order MUCH finer grit sleeves and belt. I was only able to find sets of sleeves for the 3 smallest spindle sizes, but at the time that was sufficient, and I didn't look any farther. The 80 grit it comes with, even with the oscilation leaves a very rough finish. Otherwise I have been happy with it so far.
