I use a Dewalt electric DA and it came with an adapter to attach the hose from my Shop Vac. The vacuum makes a little noise but the garage is almost dust free. Try it, you'll like it.
Many years of use out of my Porter Cables They make different models that are of great use. I have air powered da s as well. Ill grab an electric more often than not.
The Ryobi sanders and other electric tools are good value and work well. I have a big 2 stage compressor but only use it for air die grinders and small cutoff wheels. Got by for many years with just a small Sears compressor.
