@Cliff, that looks a nice unit. I don't think I'd use it enough to justify 400+ bucks though.

I just use a $30 sanding drum set in my drill press. I made a little table with a hole in the centre to keep my work square to the drum.
It gets me by, but doesn't finish as neatly as an oscillating one like yours.

edit: And the angled table on yours could be a handy feature.
