Resins which harden under UV aren't that hard to make. There was a bit of a push a year or so ago when people started looking at DLP printers.
There are perfectly good resins available for less than this one, and while there will surely be some difference in quality or properties, there's a good chance those differences will be slight. And their prices will all come down when they start being readily available by the liter bottle.
If not, then I see one thing I'll be getting into.
It's just not something that's consumer-friendly at this point.
