I have been using a SATA 4B as my “workhorse”, unfortunately parts (I need a needle) are impossible to come by.
So I managed to grab an Iwata Vault release - these are “collectible” reissues by Iwata of some classics. I have a larger one, almost big enough to be an auto gun, and I really like the Vault concept.
My new workhorse! A Kustom-CS, which very nicely comes with a pistol grip air filter (my compressor has one too).
