I have no experience with it, but if you buy in I think you do it as a hobby. The cost of film and the inability to have instant results is why Digital did so well ten years ago. It might be just as interesting to invest in an old medium format digital and see what you can do differently.

Are you wet scanning your negatives?
I took up the same task last winter but ran out of steam about half way through. I bought everything to wet scan and was going to give it a try on the old family negatives we have. We had 2x2 prints of many pictures from the 20's thru the 50's and I was amazed how well their negatives did on the scan going dry.
The time it takes to do the 35mm film I was considering hiring a company to do those.
