sleepwalker65:I've been using the SL-1600mk2 with my rec room systems for a very long time. Back in the day I had two hooked up my Rodec mixer, but gave one away. Looking back, I wish I'd kept it :-).
With a virtually identical tonearm to the SL-1200G, there are very few improvements to be found in the SL-1200G over the SL-1600mk2.
I'm now using the 1600 in my new listening room. The SL-1200G will replace it, and it will go back to the rec room. I even considered buying another 1600 from eBay for my listening room, simply because I love having a fully automatic turntable.
I settled on the G because it's new, and paired with the right cart, I do expect improved SQ. I also settled on the G because almost every reviewer and user gives it such high marks. I plan to add KAB fluid damping; and better RCA and power cables. And then sit back and enjoy the music.
