I bought mine from Steve's Wholesale Tools in 2006 for $200 and probably have somewhere between 1,000 and 1,500 hours of use on it now. It's rated for a 12.5 cfm @ 90 psi compressor. I first bought their 5HP compressor then found that one wouldn't keep up so took it back and they swapped it for the 80 gallon 2 stage Porter Cable unit. (Great service at Steve's!)
At the old house the blasting dust got all over the shop. I have a separate room for the blast cabinet at this new house & that's made a big difference. IMO, if you aren't buying a pressurized blast cabinet there's not a lot of advantage to paying for anything above the HF/Steve's Whls red $200 cabinet. They'll all leak dust and your shop vac connected to the cabinet will also. George Townsend Co. has some good replacement gloves for when your originals wear out. (buy a tube of ShooGoo to patch holes and they'll last longer) I never blast with sand due to the lung hazards associated with it. I use #10 glass beads.
Perplexed,
I have an older Dee-Blast Model 50 that I never use any more if you have any interest. 36" doors, 800lb turntable, about 8ft tall - all steel.
