I have a hand held soda blaster that I got from Redline. It works great for small stuff that just need moderate cleaning, but it won't really remove paint. ...and you absolutely need to do it outside and with the wind at your back. If you have neighbors nearby, they probably won't be happy with you either. I keep glass in my cabinet since it's appropriate for most of what I do, but I'd agree that multiple cabinets would be great. Need to build that bigger shop I guess.
I saw that block on JOMS too. That's what got me thinking about this.

Changing out blasting media is a pain in the butt, you can never get all the rough stuff out if you want to go back to delicate work. I keep super aggressive black beauty slag in mine because I mostly do old rusty car parts. For aluminum or smooth finish steel parts I just turn down the pressure and work fast. I got some nice glass beads from Summit Racing and used them at first. They are really the best on delicate stuff but cant kill the rust (or takes way too long) and do not last long and need to be changed out regularly. I did not like the walnut shells for my type of need but I do think they are good to clean grungy plastic. I need two cabinets.....maybe three. Soda needs neutralizing I believe and is hard to get the parts clean afterwards to paint. Many failed paint jobs out there due to soda blasting contamination.
