I see the 20A at Hamfests - usually priced for collectors: http://frank.pocnet.net/instruments/CentralElectronics/20A/20A.html
I do agree with your praise of the design and marketing. It would not qualify as "compact" by my definition and is far more complex than I'd like for the intended purpose. A variable-carrier DSB exciter/transmitter would cover SSB & AM, though some may object to DSB, most modern rigs can easily remove the undesired signal. Or, perhaps it's possible to add a switched filter following the balanced modulator? I don't know ...
