Hmm. I like my M4-2 more than I liked the M9; it wasn't until the M-P typ 240 that I got the same feeling and joy as with the film Ms... :angel:
But I love working with film now and then. There are simply different qualities to an image as it is formed on film, as opposed to captured with a sensor, due to the different nature of the two mediums.
Film is slow work (past the picture taking part of the game). Processing, scanning or printing in a wet lab: it all takes a good deal of time. I do tend to shoot more slowly as well, simply because a roll of film is a finite resource that I tend to conserve as opposed to the seeming infinity of exposures I can make with a digital camera and a multi-gigabyte storage card. If this reduction in pace appeals to you, by all means.
A nice film M is a thing of joy. The M4-2 in my closet is likely mine forever, I like it too much to be without it, and its very nice in the hand and to the eye. I tend to prefer the meterless Ms and either guess or use a hand-held meter with them. I'm processing most of my film with an Agfa Rondinax U or Agfa Rondix 35 daylight developing tank these days ... about 25 minutes from dry to hanging to dry with no darkroom or dark bag needed. A decent configuration file for the Nikon Coolscan V scanner and I have that mostly semi-automated now too.
Good luck deciding what you want ... Whatever it comes to be, enjoy it!
