The verdict
Buy the A1 Combo.
9.2/10 vs Neptune 4 Pro's 8/10, and it wins 4 of 5 categories. One printer. This one. The A1 Combo does multi-color, does speed, does software polish, all at a price that embarrasses the competition. The open frame is the only real compromise and most people won't care.
