I have the cyclone 150 or something like that, it's a small bench top unit. My compressor's not huge but not tiny either, I have gotten satisfactory results, but nothing near the depth of a Cooke or the like. I think more has to do with media selection than the actual unit one has. I am still searching for the right set-up on this one, and other makers aren't much help on this, they'll gladly share just about anything else, but they're pretty tightlipped about blasting.
More to the original question though, I have read somewhere sometime about makers sending their pipes to be blasted, but for the life of me can't remember where, maybe Stanwell?? It's not something I was really interested in, I want to get it figured out for myself.
