Hi, Wpydad.
I still have the 1923 Conn horn that my dad bought in '60 (see my sig; full disclosure -- we lived about 3/4 mile from the Conn factory). It was good enough for me to start playing again in '05, but eventually I did get a new horn, a Chinese clone which turned out to be a really good choice for an adult amateur player. After you get your chops and fingers back on the 64I, you might want to consider looking at one of the clones from Wessex or Mack Brass.
