Moersch has come out with a kit for Amidol users that has a longer working life than one session - SE20 Amidol Plus. Haven't yet seen it listed in US but can find it at Retro Photographic

For Ansco 130 I use PhotoFormulary kit. The developer, if topped off between sessions, has an extremely long working life. If made from separate chemicals, I understand that the glycin powder has short shelf-life and should be kept frozen. Once in solution, though, it actually helps the developer to resist oxidation.

In my limited experience with Lodima, I don't think you can go wrong with using either Amidol or Ansco 130. They both yield striking images in a relatively easy manner.
