Yes, I split Don's PPPD into individual Propylene Glycol stock solutions about 2 months ago. The stock solutions remain very stable, and working developer tray life is good.

I have been comparing 8x10 Azo Contact prints developed in Ansco 130, PPPD, Ascorbate/Phenidone paper developer and Amidol. I will probably do some Azo/Amidol this weekend. Take a look at this APUG thread:
