I'D NEVER BUY ONE AGAIN!! We too bought the HF floor model blast cabinet. Four years ago. What a POS! 1. Not enough light - replaced the interior light with two floods. 2. Leaks dust like a screen door. 3. No easy way to keep the dust down inside the thing to see what you're doing. Wrecked a couple shop vacs and etc. Still too dusty for us. 4. Gun is not reliable - sometimes works sometimes not - usually not. Replaced the gun with a better quality unit from Mac tools which helped. If I used it all the time, it would have been tossed out long ago. Cheap is what you pay for it and cheap is what we got! When I do this again, I'll built one from plywood and invest in good internals or just invest in a better cabinet to begin with.
