How many of you own an audiomods tonearm?

As stated above, it's just not good enough. 
What I'm saying is, it's not up to par with the rest of the turntable. 
If the mk2 tonearm would have fit I'd put that in the gr , because it's better.  Saying this because I compared ..
What surprised me is that the audiomods arm are so much better ! 
One simple test is let the arm rest in raised position ,turn up the volume 3/4 and tap gently with a pencil on arm / pivot/ base and listen .. 
I had resonance in tube and pivot and base .
Used no res for the turntable, cut thin stripes of cotton ( using the kind wife have for makeup removal) and put into tube . But for pivot and housing there was no good solution except for a new arm ..and I'm very glad that I found this.  Yeah it is almost the same cost as the complete turntable, but all g series were sold out and didn't want to wait knowing good and well there was room for improvement..

@iseland So do the classic 3 as well as the 6 all mount to the GR base? Are there other parts needed?

So in your opinion $100 mk2 tonearm with aluminum tube is better than new GR with magnesium tube ?

Build quality is .. 
It's all plastic on the gr .. the housing is a plastic can everything inside the can is more plastic, the pivot is plastic. 
All but the tube .. 
So yes the old mk2 tonearm is better! 
The platter and engine is way better on GR than mk2 .

@gochurchgo Jeff made an adaptor plate that fit technics base .
