P2S definitely has some nice upgrades but AFAIK isn’t available for sale yet. Between the two I’d get the P2S but if you want to take advantage of the sale the P1S is still a good choice. $399 is less than I paid for my old bed slinger printer that needed constant tinkering and hundreds worth of upgrades after buying the printer. I currently have the X1C and just saw that I’ve hit 2800 hours of print time and apart from one repair at no cost to me has been totally rock solid with the number of failed prints countable on one hand.
