@Overdriven- One more question if you don't mind. How does the battery life measure up with the drill motors? I use DTX 5000 Packs.
@BigHouse- The advantages I see are price and durability. I currently have 3 18V Dewalt screw guns in my basement that I got dirt cheap/ free and only 2 hands so I figure why not give one of them a greater purpose in life right? :-) As far as durability I've had one of them for over 10 years now and it was used when I got it. I've used it to mix 5 gallon buckets of spackle, drive 3" deck screws and everything in between and the only thing I had to do was shell out $5 forna new set of brushes. Those things are bullet proof!
