Pros & Cons
Elegoo Saturn 4 Ultra
+218x123mm plate fits a full Warhammer squad in one run, not two

−Post-processing for a full plate run takes 45-60 minutes minimum
−The purifier helps but a plate this big curing kicks up more fumes
QIDI X-Plus 3

+280mm build volume is larger than most enclosed competitors at this price
−QIDI's slicer software feels like 2020: functional but not pleasant
−Community is small; problems require more DIY solving than Bambu or Creality
−Some components are proprietary, which makes upgrades harder
