Pros & Cons
Bambu Lab A1 Mini
+Full Bambu ecosystem at $199, not a cut-down version

+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 Mars 4 Ultra
+9K resolution is a meaningful jump from 7K: finer surface texture, sharper edges on small parts
+Tilt release means FEP films last longer; $50 less per year in consumables is real money
+Built-in air purifier takes the edge off the smell without requiring an external solution
+WiFi monitoring means you can start a print and check it from another room
−153x77mm plate is tight for anything larger than small character models
−Still needs a wash and cure station: budget $50-80 extra
−Resin workflow is messier and slower to start than FDM
