I'll have to watch it again before I register my guess. I am very curious as to which you did get. I've been on the fence for months now trying to decide which resin printer to buy for myself.
Honestly, you don’t need the fanciest printer for what you want to do. The Saturn 8k or Mars 3 or 4 will be perfect for your purposes. If you’re going to print 15mm or smaller, no matter which printer you get I recommend adding some flex resin.
