Richard, from Dunnellon, Florida bought the 330 Speed-Bloc Sander. Here's what was said about it:

This Porter Cable 330 block sander is the smoothest sander I have ever used. This is the 3rd one I own, the first on bought back in the 80s and still is running. I use these on odd shapes, as I am a wood turner. The stick-it pads are very convenient, just rip off a piece place it on the pad and you are ready to go.

Features:

• Comfortable, easy-grip outer housing for hours of use without fatigue
• Solid metal frame for precision seating and alignment of bearings, motor, and fan, providing the maximum in long, trouble-free tool life
