I use a flex shaft similar to the one mentioned by the down-easter, but powered by an old Maytag motor of 1/3 hp. The induction motor is much quieter than a universal, and using the flex shaft supported on the toolrest with the 2" Power-Loc disks as primary, you can sand with almost no pressure, since you need not guide on the piece itself. Three/four good sized bowls on a 150, about half that on 240/320 is average disk life with the piece rotating. I also use 3" velcro-backed disks on the shaft, but you have to be careful with them, as there's more than enough torque to whip your wrist a bit if you press.
The inflatable bulbs with the sandpaper condoms are useful for the inside of boxes or other narrow work like goblets, though the flex disks will do almost as well, and are considerably cheaper. You want to pass on sleeve bearing types of shafts sold in hardware stores, as lubricating the sleeves collects gunk.
Since the spring is twisted, you can only rotate it in one direction, but by sanding in different clock positions on the disk you can use differential speed to sand in any direction you want.

I have been turning enough (3 to 4 hours per day) lately to burn up two cheap Makita drills while sanding some (to many to count) bowls. Maybe bad drills, maybe too much sanding....
