So i had a huge writeup, but it didn't post and i lost it, here's a condensed version:
40 lbs free standing sand blast cabinet, got it on sale @ 219 - 20% off coupon. PASS
I'm a home user hobbyist using it for small-medium car parts and brackets. Hooked it up to my shop vac for negative pressure so had no dust issues. Still it seems adequately sealed. Gun didn't clog once even with a seriously over worked pancake compressor (all i had avail at the time to test with) that was puming out warm moist air. I will probably upgrade gun in future once tips wear out or it breaks.
Lights works (though i read reports that they don't last long). Cheap sheet metal (expected). Has a lot of lips that blasting media collects on, very annoying, esp the one by the door, so media spills out when you open it. Used expensive harbor frieght aluminum oxide blasting media, 44 lbs @ $50. The stuff works well in the cabinet, though i do feel ripped off.
Overall I'm happy with my purchase based on my initial experience. If my feelings change towards the product I'll post an update. For what i paid i highly recommend it.
