Pros: Solid Power, dust bag
Cons: Not so great for larger jobs
I just used the Black and Decker 1/4 Sheet palm sander to remove the coats of stain and polyurathane from a table, coupled with the Black and Decker Firestorm 12.0 volt with the Sander attachment, and it proved just about perfect for the job that I hadn't already finished with the Firestorm.
For it's size, it is quite powerful, although for a large job like a table I don't recommend it (Unless, like me, it is already partly done). My personal favorite feature is the dust bag, because, as some may know, the dust blown up from polyurathane and considerably old oak stain is very unpleasant.
As a whole, I think that for a small job, this tool is very much worth having, as well as relativley inexpensive.
