Spotted this as I've been wanting a second resin printer (technically my 3rd now, but I wanted two Saturns) and found this had dropped in price again. Pretty sure they're clearing out stock as they have the Saturn S, Saturn 8k, and Saturn 2 now. But this is a great printer with a good build volume.
There's one on the store for a few dollars more - I reached out to them today to ask what the difference was but I haven't heard a reply. There's also one for about $419 from the elegoo_printer store, but it says it doesn't ship to me (Brisbane).
I think this is pretty close to the lowest price it's been in the past.
Reminder to not touch even fully cured resin with bare skin unless it is specifically stated as bio-compatible. Always wear gloves. Run it somewhere with very good ventilation or a fume hood/ghetto fume hood
