I actually have this model and have been using it as my main source of amplification while waiting for a new amplifier to arrive (one of my JC-1s broke). I think it is quite a good value used (about $2K) since you can just plug in a digital source and don't need an external dac.
There is one huge caveat IMHO with Technics implementation of this technology in my experience with the SU-G30. The analog input is digitized, and that conversion adds a significant digital flavor to the sound coming out of the speakers compared to a pure analog setup (in my case BHK pre and JC-1 amps).
