I'm shooting chrome film like crazy and I've ready to delve into home E-6 processing!

I've got the equipment and the mechanics nailed down but now I just have to source the chemistry.

I've settled on the Kodak E-6 (5L) kit, but many of the typical suppliers seem to have really low stocks (or "unavailable at this time").

I'm in the US - can one of the US, E-6 home processors give me a line on a good and reliable supplier?
