If I recall correctly the CR2 Ion XT had a different beam profile than the regular CR2 Ion, one with a more typical parabolic reflector and a clearly defined hotspot?
In that case, unless you are particularly attached to the CR2 Ion XT, the newer Aeon (designed and made by the same guy -- Enrique/Photons Intl/Muyshondt) is exactly the same size and very nearly the same design, and actually far easier to get, since the CR2 Ion XT was a pretty small limited run. It also came in Ti or HA aluminum.
In any case, good luck on your hunt, you misspelled your username, posted in the wrong forum (should be Custom B/S/T), but welcome to CPF!
