Help! I need the rechargeable battery for the Fuji GX680. For the original one, not the GX680III. Seems that I read somewhere that there was a AA battery pack for the GX680 III that can be made to work with the original 680. Can anyone confirm this? Was there a AA battery pack specifically designed for the original 680? I can't seem to locate either the rechargeable battery or the battery pack. I have tried the "big auction", and several of the major photo supply houses, with no luck. Any ideas?
