I have only recently started developing myself. I thought about this for a long time as a) I wanted something with good shelf life b) I wanted something with good documentation and c) I knew i wanted to stick with one developer until I have more experience. I chose Ilford LC29 as I am then using an "all Ilford products" process. So far its living up to all expectations. I am nearly through my first 250ml bottle, and its no different to when I started about 6-8 months ago. Mix is 15ml + 285ml at 1:19 for one 35mm film. Works for me.
