I have the bosch. I like it but the sanding pad wore out fast. I got a portercable and the pad has lasted much longer. I don't know the normal time before having to replace them, but the bosch was only after a month. And that is what led to the PC purchase, because Lowes and HD don't carry the pads for the bosch(at least at the ones by my house) and I needed one that night. I like the way the bosch works a little better than the PC, but with the stores around not selling parts for it, even though they sell the sander, makes it a pain.
