It's been several yrs since I looked into this but it seems to me that the only actual one you could get was from a guy in Puallup(I know I miss spelled that, sorry) WA. He was specially building them as orders came in. I will try to remember his contact info/find it for you if you are serious. The cost was just over 2500 for the charger and all components at that time.
that would be great if you could find that info. appreciate the help.
