Thanks Roland for the advice.  All excellent points.  Much appreciated.  The through the mount cabling of the Mach2 will be a nice upgrade for me and will open the door to more automation in my imaging.  I won't have to worry about personally monitoring meridian flips and re-arranging cables to prevent snags, etc.  I hadn't planned on a hub - my ZWO camera has a two port on-board hub - but I am now thinking about that option.  Thanks again.
