I have had good luck with Dimezone/Phenidone and Ascorbic Acid developers in the last few years. I mix my own but there is a formula for E-72 on the jackspc's site- http://www.jackspcs.com/pde72.htm which looks reasonably alike to the Suzuki developers mentioned above.
I use more carbonate, and Benzotriazole in place of KBr. Mix the Dimezone/Phenidone in Propylene Glycol to make it easier to measure. 10g goes a long way. I have read that Dimezone lasts longer in solution for what it is worth. I have gone more than a few months without printing and a half full container of used developer was still fine.
