LPD is a good one to try.
The tone can be adjusted by varying the dilution,;straight leans cold, 1+4 leans warm, and you can use whatever dilution gives you what you want.
I keep my stock in a recycled wine box, keep the diluted solution in a nondescript 1-liter plastic bottle. I have another bottle for working solution.
I replenish the working solution by simply topping up to replace what's lost with each sheet, which even at 1+4 seems to be more than adequate.
It is like the Energizer bunny it just keeps going and going and going too. The only reason I've replaced my working solutions in the last few years has been because of my stupid mistakes and contamination coming fron the tray/paper; the developer itself never seems to die.
