"He who marches out of step hears another drum." ~ Ken Kesey
I agree with the earlier post about more colors. I went with a 6 color. I say all the time that my next press will be at least 10 colors. I would also STRONGLY suggest getting a certified tech to instal for you. If this is your first auto press you may not know if something is off or not right until it is too late.
Do yourself a favor and look at Marcodie. You can get the press in any registration configuration you want (Tri Lock MHM or Pin). Very high end press at a Diamondback price. http://marcodieusa.com/
