Compressor ?

Both those compressors will be too small to handle even the cabinet sandblaster. The 3 cylinder head used on the 5 hp one is the same as I have on both my 3 hp electric, and on my 10 hp gas. With both those running, It just keeps up.
I have the same compressor head as the one on the 7 hp compressor you are looking at. It now resides under the bench, replaced by the 3 cylinder one. These are both light duty compressors, and I think Princess somewhat overrates their CFM.
I think, if you were going to buy from PA, that you would need at a minimum the 5hp industrial compressor 0412189 ($1699) or way better would be the 10hp 0412999 ($3000).
But as these are getting up there in price, why not hit some of the closeout auctions around your area and try to buy a old industrial compressor from an auto dealership closeout . I got my 10hp Devilibiss for $700, and I have to spend another $600 for a single phase motor. As a bonus, you can actually buy parts for the divivlibiss; try and do that with a princess auto compressor.
When you do get your air compressor situation sorted out, the cabinet is a great purchase. I found that I had to remove a tiny rubber washer that was on the needle in the gun, otherwise the airflow in my gun was poor. Once I had done this, my cabinet blasts as good as the big one I used to use at work. However, it comes back to the compressor; you will need a lot of air.
