Theres nothing like the real deal, and you won't find it at the hardware store. Get a six-inch (hook&loop) random-orbit variable-speed sander with the vacuum hose connection. I have the Porter-Cable brand, an industrial quality tool that comes with a case and hose. Another quality brand is Fein, and a third that people swear by is DeWalt. Connect it to a shopvac, doesn't have to be a large one but it has to have a bag so the dust doesn't destroy the vac bearings. Some people use a bucket-style water trap like professional drywall installers use. Use with a ground tarp as not all dust will be caught. Always use a respirator, and other gear as needed.I had to find an industrial power tool store in the yellow pages to find mine. I see Fein in online marine suppliers. Sometimes yards have them to rent. The little orbital finish sanders will work for small jobs, but will vibrate your hand off on big jobs.Good orbitals are very non-agressive. They will feather an edge daintily, or remove heavy bottompaint without "packing up' the sandpaper depending on what grit you use. They are a pleasure to use and worth the extra cost.
