Pros & Cons
Bambu Lab A1
+Full 256mm build volume, same as the Combo but $100 cheaper
+Bambu's reliability, slicer, and support at $299
+500mm/s speed that's calibrated and ready without tweaking
+AMS Lite upgradeable later when multi-color becomes interesting
−Open frame: ABS warping is a real problem without modification
−No multi-color in the box: the Combo is $100 more and includes it
−The upgrade to A1 Combo is tempting enough that many buyers regret not doing it upfront
Elegoo Neptune 4 Max
+420x420x480mm with Klipper for $469: the price-to-volume ratio is hard to beat
+Direct drive on a bed this large is unusual and useful for flexible materials
+Klipper gives you full control to tune speed and acceleration for the mass of this bed
+Prints full armor breastplates in a single run
−Open frame at this scale means ABS warping will ruin prints without serious prep
−The sheer footprint means a dedicated table minimum; don't try to share desk space
−Slower effective speeds on a 420mm heated bed: physics wins eventually
