I believe my dad just bought a sand blaster at the local hardware store, like menards, same with the one we have at work, same thing, seems to work great, but If you try and use the heavy duty black sand blasting sand it will sometimes plug the smaller tips up, kind of a pain but thats the only complaint.

I believe it was cheaper at the store though, plus no shipping! Do you want a cabinet style? What are you blasting?
