All the Beltronics 65 series detectors (ie RX65 red, RX65 blue, and GX65) are on back order on the companies site. Maybe this indicates that belscort is planning to update these units? Maybe giving them the same lens that they recently gave to the X50 black?
By putting them on back order, it prevents people from buying them now, and getting upset when the new version comes out a month later. Its just that all those units being on back order at the time seems very odd.
