Harbor Freight sandblasting cabinet...

The local chinese tool company up here (Princess Auto) sells those clear window protectors. Its a consumable for the cabinet. The glass should be tempered and not cheap to replace. If its a siphon cabinet they don't work worth crap without mods. Just google 'cabinet metering valve mod'. It makes a huge difference in performance and stops plugging. I run the cabinet with about 2 cups of media in it.
