My old 6 in pneumatic sander needs replaced, I want electric with dust collection.

You will NOT be happy! If you are set up for pneumatic and have used pneumatic, there is not a single electric sander on the planet that will make you happy. Heck, I even have every Festool sander made, and given to me for free, and I won't use them over my standard Dynabrades.
