Yea my compressor isn't no where big enough to run a DA so I did alot of research on the electric ones and that one seemed to be the best bang for buck. Harbor freight had their brand, warrior for 39 I had a coupon and got the Bauer brand for the same price. I feel it's probably better than the warrior one. I got to find a little 3 inch angle sander for the hard to reach places that 6 inch wheel is hard to fit in tight corners. And I gotta upgrade my air compressor soon. I can't afford the size I need and I don't have a 220 hookup in my shop for a big one. So I'm thinking about trying to find another used 21 gallon one and teeing them together. That would give me 41 gal and should double my cfm. I also considered of I can find just a tank 40-50 gal for cheap buying it and buying one of those 24 cfm pumps with the pulley and just running a gas motor on it. I have a spare predator engine brand new in the box
