Sand-blasting cabinets?

I recently purchased the same cabinet. What vacuum are you using and where did you get it?
http://www.lowes.com/lowes/lkn?action=productDetail&productId=141554-20097-9520111&lpage=none I am using this one from lowes...it is quiet....At the top you have a plastic plug that you blocked off the hole with....mine came with a vac hook up which I lost a few years ago...so I just cut a hole in the plastic and I put the male end of vac right in there it works good.....I can get you pics if needed....I would try to get a bigger vac, like more suction power...but this one works...for the 60 dollars
