keyofnight: That's why I mentioned Lyga's method, since it seems to be the least expensive option. I plan to try it sometime, although without the sodium carbonate, since I'll be developing at regular dilution and temperature.

But as far as the kits go, I like the Rollei Digibase kit. It adheres to C-41 standards (bleach & fix instead of blix), and the liquid concentrates make for indefinite storage and the mixing up of however much you need.
