This discussion got me interested in the 1200G and a local dealer has one in stock. I looked up reviews, and found Stereophile's Technics SL-1200G turntable | Stereophile.com.
As luck would have it, Stereophile compared it to a Garrard 301. I have a 301 which I am fettling and since there was no clear winner, I will keep on with the 301 for now.
Recalling the discussion earlier in this thread on wooden plinths, I note that my 301 came mounted in an SME wooden plinth. I have built an inner structure of thick MDF slabs separated by constrained layer damping. The 301 mounting board floats on the inner structure, which in turn sits on three IsoAccoustics OREA Bordeaux isolation feet. The SME plinth and integrated dustcover are air-gapped from the inner structure so preserving the original aesthetic while adding a lot of damping and isolation.
