I needed to replace the gun for my cabinet not too long ago. Picked one up from McMaster Carr. http://www.mcmaster.com/#abrasive-blasters/=ne05ay I didn't need the trigger version as my cabinet has a foot valve. I'm a lot happier with this new gun over the old one. I have a mix of media and it all goes through the gun fine. You're compressor will need to keep up with it!
