I'm looking for the AA 9A60 model. Anyone have an extra they are willing to part with? I'm also looking into trying to make one myself, but that may be more work that I can give a project. EDIT I might also be interested in the KeyDigital KD-VTCA2 but I'm unsure about the dipswitches. I won't like this if I have to change these settings. If not that may work too. Thanks.
