I Know this may be too late, but I've been using MMX for two years ( my first conversational software)on a G&L RS-150 DCC, and I like it plenty. I learned FLB seven years ago, and LK cmes four years ago, and Measuremax is superior, the only area that it lacks is no CADD support. I had minimal training, by an operator that took the free training. The rest I figured out myself.
