I really wish i had room in my garage for a cabinet but I don't. I'd use the heck out of it for sure. Had to get creative with the tub. I just put a tarp and some lumber over it when i'm not using it and stays dry. Heard you definitely need to do some work to the seals on the HF cabinets if you don't want an eventual mess.
The $120 HF blast cabinet does need some work.
1 The fabric between the arm ports and the rubber gloves was junk (on mine anyway) and I replaced it with HD canvass.
2 The plastic window protection sheets they supply (3) are a pain to put on the inside of the cabinet. They are only available on line. I flipped the screws on the window retainer, put them in from the inside with nuts on the outside and use wing nuts to hold down the retainer. I can remove the window to replace the plastic protection. I use clear static cling plastic sheet, the stuff used to cover windows in the winter.
3 The bottom is a shallow slope and the media doesn't slide down to the bottom for the pick up tube well at all. I replaced the bottom sheet metal with a deep slope and made the media drain from the bottom instead of sideways.
4 You need light inside to see what your doing. I put a under kitchen cabinet light and painted the inside white (SPI epoxy).
5 The plastic port for a vacuum to clear the dust fits no hose I could find so that had to be machined larger.
6 The ceramic nozzles don't last very long I replaced that with a carbide nozzle. I had issues with the jet inside the blast gun, made new ones, don't remember the details on that.
7 Almost forgot to mention all the foam seals had to be replaced and all other seams needed calk.
So I bought it to clean and blast small stuff because I didn't want to spend the time to build one. But I could have!
I do use it quite a lot now that it works.
