Pros & Cons
Longer Orange 4K V2
+Better light uniformity than the V1 means fewer dark patches at plate edges
+WiFi at $199 is a feature the original didn't have
+Compact enough to store in a drawer when not printing
−4K resolution is dated: the Elegoo Mars 4 offers 7K for $149 with better community support
−120x68mm plate is small even by entry-level standards
−Longer's support community is thin: problems are harder to solve than on Elegoo hardware
Phrozen Sonic Mega 8K S2
+330x185mm plate is the largest resin build area in the consumer market at this price
+8K detail across the full plate without the hot spot degradation that plagues cheaper large-format LCDs
+Dual tilt release on a plate this size prevents the vacuum seal failures that ruin large prints
+Professional-grade aluminum build quality that handles the stress of frequent full-plate runs
−$749 for a resin printer is a serious investment, plus $80-120 for a wash station to match
−High resin consumption: a full plate run uses 400-500ml, which adds up weekly
−100mm/hr speed is the same as entry-level machines: the size advantage doesn't come with a speed advantage
