Hi All,
Thanks for all the continuing advice and thoughts. I'd just thought I'd update you all on where I'm at now:
I've since sold the 8X10 and a 5X7 is on the way. Much more cost effective to run and I can still very nicely scratch my contact printing itch.
I love my M6, it's small, light, stealthy and pretty quick, but most of all I seem to love the idea of it, moreso than shooting with it. It's a joy to use but doesn't quite jive with the way I take pictures so it and it's lenses are up in the classifieds here. Part of my decision is financial. I have a lot tied up in it and were I able to let it sit for when I get the urge to mess about with it I would but I can't right now. I'm positive I'll buy another M one day but it's not the right tool for the job at this point. It's not working as a primary camera for me.
I've also put aside the idea of a MF RF as my "notebook" camera. The close focus issues are the real deal killer for me at this point. I also really had my heart set on 6x7 as I'm not sure that 645 would work for me, mainly because I tend to shoot a lot of horizontals and all of them run the film vertically. The Mamiya 6 is an option but I'm not sure how I feel about the square format, I need to consider this more.
That said what I've wound up on at this point is my trusty Nikon N80. Small, light, AF, AE, pretty quiet, and built in flash. Paired up with a 35/2 and 85/1.8. I'll probably add a second body as they run about $50 these days and dedicate one to each lens. I also have a 24/2.8 that I use on my DSLR to give me a 35 so that's available for wide duty. Not as glamourus as a Leica M kit but very effective and useful. I'll be able to make photographs with it and as much as I love obsessing over gear, that really is what matters.
Please feel free to share your thoughts and feelings on this, I'd love to hear them.
