Hi, Brad -
You may have already ordered a bag, but if not, you might want to look at Ellington's "Hollister" field bag or satchel. They seem to be available on "clearance" for about $100. I have more camera bags than I care to admit, including some of those already mentioned, but this is the bag I tend to grab most of the time now. It's tough and low-key, and will fit a Mamiya 6, Leica, film, light meter, etc. I had my mother-in-law (I knew she was good for something!) make me a padded insert out of a sleigh pad my kids have outgrown.
