I was able to finally get another negative carrier for my Zone VI, 3 of them came up for sale on E-bay and no one bid real high.  Last year when I tried to get one for 6x6 the bids went up to over a hundred bucks and I wasn't going to pay that for a negative carrier.  This time 3 came up for bid, a 6x6, 6x7 and 4x5 all for the 1st model of the Zone VI which is what I have.  I bid on all three but the 6x7 was the only one I got.  I could still use it for 6x6 I'll just have to crop on the enlarger.  I do have a 6x7 camera, the Koni Omega 200.  Great Camera.
