Just to add to the debate, I lucked into a commercial unit that an electronics company was disposing of. I could not restore the cars and motorcycles I did without it. The downside is it eats a lot of air. My 5-hp compressor cannot really keep up. Some modifications have really helped. Changed gun to one that allows jet changes to better match the available air and extend working time. Improved lighting so I can better see what I'm doing. Cut cabinet and installed a larger window. Cabinet already has large filter system. System is now much improved but I still wish I had a larger compressor. Have learned to be patient. Forgot to mention this is a 110v.
