selling my plaubel veriwide (6x10) I bought a well used cambo wide, a 47mm xl lens and a 6x12 back for just under 1000$ on the big auction site about 18 months ago. the back was a cheap chinese one, there were (manageable) leaks and I have difficulties with red windows for film numbers, so I got a sinar vario on top of it. that's a nice couple, not too big, not too heavy and easy to carry around via the integrated handle. I had a cheap custom viewer made for guesstimation of framing and I use a polaroid pack 100 back in case of doubt. I also got a ground glass, but I'm not too much into ground glass framing.
