There is also Kodak's DK-93. From Anchell's Darkroom Cookbook:
p-aminiphenol HCl 5 grams
Sod. Sulfite 30g
Sod. Metaborate 20g
Pot. Bro. .5g
For warm tones on paper, use w/o dilution dev for 2 min. For colder tones, 2x the Sod. Metabortate and dev for 1-2 min.
You can also use this dev for film.
I included this dev as it may use more readily available chems.
