Technics SL-1200GAE or VPI HW-40 or …?

If you are still looking at weights and mats, I tried a bunch of weights on my 1210G and somewhat surprisingly came away most impressed with the Origin Live Gravity One--which weighs the least of any that I tried.  It's really impressive, everything was positive with no negative side effects--which I find is unusual in this hobby.  My least favorite by far, was the MoFi Superheavyweight, which took the 1210s natural dynamics and stole away with them like a thief in the night. 

My Mat is the Stein Music Perfect Interface, which I also really like (but it's not cheap).  Origin Live also has a new one that I have not heard that has gotten some raves.

Yes, if you can't find the Original (Goldmund Relief Mat), the next best thing is the Oracle hard mat. 

I used to recommend just using another record - under your record - as your mat. I was laughed at, until clearaudio introduced Their record mat, which was (yes you've guessed it), -a blank grooveless record.

The (built in) mats found on SME turntables are also very close to the properties of a record.

PS: the Atmasphere 208 was a wonderful table.

PS2: there's no need to spend 10 years on developing a mat.

Agreed. I've recommended using a 10" record as a mat for years.
