I have had an earlier version of the same Porter Cable sander that I bought in 1990! I am a street rodder/sailor and have used the old sander on many heavy duty projects from sanding the bottom of my sailboat to removing decades old paint from car bodies, to finish sanding of Bondo areas. Unfortunately, the old sander gave up the ghost after 23 years and it was not cost effective to repair it. There was NO hesitation about a replacement. The new sander is actually a little heavier and performs just as well, if not better....plus I paid about the same $$ as I spent for the sander in 1990.
