OMG $79 more! That ruins everything!
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.

I'm not suggesting Formlabs would do this, but advertising the $79 add-on and then making very few of them available would be a way for a manufacturer to look open while actually not supporting openness.
$79 per tank.
Along with some issues with the screen and the non-pro resins.
It’s anti-consumer.
They want to be the HP/Bambu of resin printers.
