Looked at the Mark 7... $4,000 entry cost (and up to $13,000 fully loaded) made me realize I would need to be in the manufacturing business to justify it. For a hobby reloader like myself, even the Dillon 1050/1100 was a little much considering the cost of setting one up for 5 calibers is $3,000+. So, I settled for the Dillon 750, which I am now in over $1500 for 4 calibers. Not sure I shouldn't have kept my RCBS Pro2000 and been happy for the couple thousand rounds a year I may load, but that is officially "water under the bridge" now.
