Before investing in a blasting cabinet be aware that you will need some sort of vacuum device to go along with it and if you think you can get off cheap, think again. A good, dependable, LONG LASTING, vacuum is a must.
Blasting cabinets generate large volumes of mico-fine dust that clogs conventional filters (like shop vacs) very quickly and it's extremely frustrating to have to stop work to clean an inadequate filter only to have to do it again soon after.
Another less critical but important feature is a hopper at the bottom for emptying the abrasive so you can change blasting media quickly.
BadBoy has a what appears to be a nice unit for $800 and it includes a vac.
Of course, you will have parts that are too big for whatever you buy so find a tombstone company that will blast those for you.
