I do it for the enhanced sense of ownership of the process it gives me.

I like this idea. I think it would be fun to make ones own chemistry and there is something new to learn. Learning is always a good thing.
I would like to make Ansco 130, to find out why so many people love it. As well as PC-TEA, D-23 for a start.
What bother me is how expensive the raw chemicals are. It is really cheaper to buy finished products.
