All I can say is to keep watch on flembay and craigslist. Dont hesitate to check all surrounding locations for your state(whole country)on craigs, and ask them to ship. I have four C-700's, three set up and the fourth is in storage(its brand new). You can always mask a 6x6 carrier if you dont find a 6x4.5, the 6x7 is even harder to get. I also have a Pro45 w/turret and tons of lenses. Unfortunatly, I only have one 6x6 carrier for the C-700, or I would offer you one. Congrats on getting IMHO a great machine.
