The pics are staged. They don't show just how messy open air blasting is. To do it, you have to have drop sheets for media recovery, and the (abrasive) stuff gets into EVERYTHING in the surrounding area/downwind.
We have a large cabinet out in the shop at my work, so it's a non issue for me, but id I were looking for home use, I'd look into a bench cabinet before that. Our local budget tool store has them on sale every few months for $189 (120 quid).
