On the topic of MEC presses, it's interesting to note that the single-stage 600 Jr can be set in either of two positions with the bolt and holes in the center post beneath the shellplate. In 12-16-20 gauge this allows setting the press either in 2-3/4" mode or 3" mode. The recent 10 gauge example I have has the holes set up so it can be switched between 3-1/2" and 2-7/8". Pretty cool.
