You can get a portable unit like the one
I posted on the 2nd page for $60 cheaper at HarborFreight (and they carry media too) and the media was less than $50. I used a big cardboard box on sawhorses with a 5gal bucket underneath to catch and reuse the media. I ended up buying the HF bench top unit on sale for $109 this morning and it comes with the gun too, assembled and ready to use. I plan to do a lot more blasting! I just finished the shroud posted above and it looks great, all of the clamps, screws, nuts, etc. This bead does not remove the plating if you stay back about 5" at 60PSI and the 1/4" tip.
