I bought this 1988 DA model. died on 08/15/2017. Not bad for an air tool. This is probably one of the most underrated and best value DAs out there. It's very quiet, uses very little air compared to others (4.4 cfm) and runs very quietly and comfortably. That's why I was so happy to know that Sunex still makes this model. If this one lasts another 29 years, it will hold me. I have run Hutchins and Dynabrade as well as several other leading companies. I'm still talking about the price, nothing beats this DA.
