Why use the thumbnail from an $800 Anycubic Photon Mono X on your sub $250 printer video?
No saturn 4k in the rankings👀
The Anycubic Photon Mono should be a clear winner here, but… The FEP film replacement is very expensive, because in stead of simply replacing the film, you have to buy a complete frame with film glued to it. Also – The LCD screen on any printer of this type has to be replaced after been used for a long time (admitted – without any accident it should last for about 2000 hour printing time, but still). That should not be a problem if it was not for the lack of availability of this replacement screen. It is simply out of stock everywhere. The same goes for the replacement FEP film with frame. There are ways around that by buying a replacement vat for example, but that adds to the costs of the initial buy.
For now I dubbing between the Creality LD-002H and the ELEGOO Mars 2 Pro (that printer is the mono version of the Mars 2, but is slightly more expensive, so I get why you did not included this printer). For both all replacement stuff is easy obtainable. If you use a printer for a longer period, that's simply crucial.
