Not a cheap resin by any means, but generally acknowledged as one of the more affordable consumer-grade high-strength resins for home SLA 3D printers. According to Honey's price tracker this is the cheapest it's been since July this year. Considering a 1kg bottle Elegoo grey is about $55, this is a pretty good price.
I've been printing some stuff that needed more accuracy and strength recently, so the next time I go to print it I will use a bottle of this instead, or add some of this to some cheaper resin which apparently can help.
It's cheaper on the Siraya website by $5….
