I always wanted Porter Cable belt sander. I had an old Ryobi and it lasted for years doing continual carpentry work...but I knew it was not a great machine.  I got this 352VS from Amazon 5 years ago, put about 8 hours on it (no longer doing carpentry full-time)...and a few weeks ago did some light-duty sanding on a piece of furniture.  The belt started slipping and then stopped.  Opened the tool and found the drive pulley is plastic, not metal.  It had sheared at the "hub".  Seems foolish for Porter Cable to have replaced at 40-cent metal pulley with a 15 cent plastic pulley but that's what they did.  My local tool repair guy told me they did this for a while.  Now they are back to metal, supposedely, but who knows what else they changed.  Now that DeWalt has bought Porter Cable, who knows what things will be like in the future.
