Cabinet Sandblasters?

[Duesey]

I've looked at skatblast on ebay often and it was one of my favorite choices. I'm just curious if they work good. I can build my own, but it's hard to find the time. Do the systems with their own vacum work better than the shop vac ones? The shop vac ones look a little hokey. Thanks for the responses. The top of line snap on pressure systems looks nice but it's out of my price range. I'm currently putting a quarter section on a trailblazer for the wife and I've got a 53' eldorado and a 57'? T-bird coming in this winter for paint. Otherwise I would like to tackle building my own but this winter is booked getting these two cars done. Thanks again for the responses, have any of you guy's built one?
