I buy the Dewalt refurbished tools at half the price of a new model

Same here. I bought a refurbished Dewalt RO sander about ten years ago.
Even after doing a complete bottom job on a previous ketch--sanding the gel
down to a very thin layer followed by epoxy barrier coats and
antifouling--it still runs fine. Recently I bought a Porter Cable
right-angle RO sander for the same job, upcoming on the current boat. It
theoretically should be quite a bit more durable, but I doubt if it will be
any better after the job is finished than the Dewalt.
