New Technics turntables

Different strokes for different folks.  You've got good reasons to do what you want to do, Abery, but if your requirements were not what they are, the point is that the 1200GR is almost certainly the "better" turntable, given that the differences in favor of the 1200GR may not be meaningful or useful for your needs. In other words, go for it.

You've got me thinking. I'm willing to bet the built in pre of the 1500c is no better than the cheap options like the Schitt or even this one (I have 78's as well---and will be getting a dedicated mono/78 cartridge)

I'm now leaning toward the 1210GR. I already ordered an ATVM540ML cartridge. I'm also thinking of the MoFi Studio phono (mono button) since I have many mono albums. The Studio Phono looks like the best low cost option. Eventually I would like to get a Graham Slee Jazz or similar for non RIAA settings. 

The studio Phono is now on its way. Next up will be ordering the 1210 this weekend

Does anyone actually have a 1500C? I'm about to take the plunge as it seems to be so much turntable for the money and I'm fed up of stuff needing TLC
