Tonearm for Technics 1200GR


I’m looking for a medium mass arm to replace the stock arm. Whatever arm is suggested it should have an armboard that can be bought for it as well. I run a Soundsmith Carmen MkII. 

Id like to keep the new arm under $1500. 

I found a Jelco TK 850s, but it appears to be a high mass arm. I also found a Timestep T-609, but it appears to be a high mass arm as well.

Chak, the Triplanar mounts in much the same way as a Reed.  I own one of each.  I do like the Reed, too.  But Raul and I agree that the base SL1200G tonearm is very nicely designed and manufactured.  I had a very close look at it in May when I was in Tokyo.
No problem, but i understand why someone willing to change the arm, even in terms of design i can understand that (not only sound quality). The Reed is so much better than any Technics arms including the EPA-100 which was my main arm before i replaced it with Reed 3p "12. I am not familiar with TriPlanar. But any arm with fluid damper collect dust in that fluid bath (for this reason i don't like KAB fluid dampers for technics tonearms, i don't use dust covers on my turntables). 

 
Nothing wrong with the arm on the GR.  The Triplanar and the Reed both cost considerably more than the table so would be a big investment.  I'd live with the arm for awhile until you get a better sense of its qualities.
Thanks for everyone’s comments. I have decided to keep the tonearm. 
Currently I use an LP Zupreme head shell, a KAB fluid damper, and a Funk firm mat with a deer hide mat on top of that. My Phono cables are Purist Audio Design Venustas Praesto Revision and an old Audio Research PH3SE Phono pre. This all gets fed to my BAT VK3ix preamp and eventually makes its way to my Thiel CS2.4 speakers. It all sound really good for older gear but I guess I like fiddling with stuff and that’s why I was thinking about improving my tonearm. But I think my money will be better spent on the cart after reading your comments. I also thought about a copper mat to add mass but I’m not sure how much more weight the bearing can take. 
The bearing friction of the Technics is lower than 5mg where no one of the tonearms named here has.

All Jelco have friction between 20 and 30 mg. and the manufacturer does not want or do not want to apply better bearings.
It is not possible to use a Jelco on the GR, it means taking steps backwards not upgrading!
