I've only tried Michael A. Smith's formula, so I can't comment on the others, but I've heard they don't last nearly as long and don't work as well. Check out his site for the formula, developing times, technique, etc.

You should get your amidol from Mike Jacobson at:
Mike is quite familiar with all of Michael Smith's formulae.
You will also need sodium thiosulfate pentahydrate (plain fixer), citric acid, sodium sulfite and sodium (meta)bisulfite. Also, I put benzotriazole in my amidol but I seem to be in the minority.
Figure about 5 lbs. of fixer crystals for each gallon of working solution. I have gotten pink stain on my prints when using ammonium thiosulfate based (rapid) fixers with amidol. I didn't always get it, but it absolutely ruins your prints when you do. Better to be safe than sorry when working with precious amidol and Azo.
