Pros & Cons
Bambu Lab A1 Mini
+Full Bambu ecosystem at $199, not a cut-down version
+Footprint smaller than a sheet of A4 paper
+Prints reliably straight from the box, no tinkering required
+Upgrade path to multi-color via AMS Lite if the bug hits later
−180mm cube is genuinely limiting for anything beyond small parts
−No enclosure means ABS is a non-starter
−Multi-color costs extra; the Combo does it better
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
