Looking for advice on a DA Sander

[D-n-Tyke]

Getting ready to start in on all the body work and am in need of a new DA sander to make the sanding go easier. Plan on using it for all aspects of the body work. What are the better ones out there, what are the ones to stay away from.

Also, are there other pneumatic sanders that I should be looking at the work well on the truck bodies.

Body work will include stripping the body completely down for a total repaint. Current condition is one home respray over factory paint.
