Eric, if you do it right, DIY developing really isn't that much of an effort. I thoroughly enjoy the simplified process i've created for myself. But oh well, different strokes for different folks.
As for me, I've only recently delved into MF with a 6x7 Bronica, and have come to realize that this format for me can never replace 35mm, but will complement it very nicely. MF gear is simply too heavy and the lenses are too slow, but I would never give up the advantages of a big negative in certain situations.
But on the other hand, I could see myself taking nothing but a 6x6 TLR on a holiday instead of all kinds of 35mm equipment…
