The ComMarker B4 60W MOPA earns the top rating because no other machine under $1,100 combines 60W JPT MOPA, LightBurn support, and a 60W power level. The standard 110×110mm work area is smaller than some alternatives — tumblers require a rotary and the work area is tight for large pieces. It is the benchmark for serious makers and small business operators doing metal-focused work. Two things to verify before buying: first, check whether ASIN B0CGX9TBGQ is in stock — the B4 line is end-of-life, and if both the B4 and B6 MOPA are available at similar prices, the B6's autofocus and updated form factor make it the stronger long-term buy. Second, budget time for LightBurn setup — the COR file configuration takes an hour the first time. For experienced users who know what they are buying into, this remains the benchmark purchase under $1,100.
