Mechanical Cockers are very friendly for those who can read, and follow instructions. All the super secret timing stuff that made them supposedly not user friendly, is out on the web numerous places, in a step by step directions format. Most of the brass rams on the early guns were made by Clippard and are still being manufactured. I am partial to slider frames myself on a right feed body, but I am old.
I miss the days where the Autococker was the must have gun. All the knuckleheads that had to tamper with their guns to make them better, just allowed me to pick up out of time guns, for pennies on the dollar.
