I have a used scat blast cabinet by tp tools. These are high quality cabinets and this cost over $1k new. It has been used almost everyday for about a year, so it shows so wear. Part of the grate in it has worn away so we just screwed down some sheet metal to cover the hole. Fully functional and comes with several extras. It has a vacuum system, vibrator that keeps the media flowing well and it has the wheel kit so it can roll around. It will need a new light in it and it wouldn't hurt to put a new nozzle on it as well, but all parts can be purchased online at tp tools. Functional and ready to work. You will want at least a 5hp compressor to run this cabinet, it uses a lot of air but blasts very effectively. We use this to blast and prep for cerakote. Its well used and dirty but still functional.
Looking for $250, and located in Crossville.
