You need to buy a tank anyway, which is $50 or so — that works with their new Alpha resins. The slightly more expensive tank is necessary only for their engineering-grade resins (only a couple are certified for the Studio 1 so far) and 'OMM' (Open Material Mode), which as mentioned above, comes out of the box on the Studio 1.
