Sorry, It didn't work out for you.
I have struggled with the same thing in the M line for awhile now. I really like the M8, but am just not using it enough. It has really turned into a personal camera only and other needs are hitting.
You know the drill, too many cameras and not enough time. Several things are going on the block this week.
Another struggle on the film side is how to manage color or B&W. I finally gave up on color film when developed locally here in Phoenix, as the two "Pro" labs leave it scratched or looking like someone moonlighting from KFC (grease) processed it. I do love real B&W, so have taken to developing it myself and scanning on a Nikon.
Just sold the M8 & am keeping the M7. That means that I'm gonna sell the 28 cron also, as I don't like that focal length on film even though it is a great lens. Personal work with the M7 is going to be 35/50/90, which are the only frame lines in mine.
Digital still stays as that is what pays bills, but in the form of a Nikon and the Hasselblad.
Hopefully someday, you will play film some more. Not getting into the film vs. digital debate, as they are different and both great. Funny thing is that I'm getting more enjoyment from shooting the M7 in film than from the M8. I just naturally slow down and really plan the shot.
You may find that posting film to somewhere for development is feasible. I do a fast single pass scan at 8 bit of the entire roll to see what really deserves more time and then do a good scan on the keepers only. It really saves time.
Best,
Ray
