Johnnyb53, to add one more supporting comment: isolation is isolation. The success in isolation depends in part on controlling resonance, to keep them from drumming their way through the turntable system. The isolation required for DJ applications is in fact no different than what is required for home audiophile applications. Put a killer arm (or just use the stock EPA-120 which is already quite decent) and a killer cartridge that tracks at most at 1.75 grams, and play a record. Bang on the table the turntable is sitting on. You'll get nothing. The cartridge/arm will not move out of the groove. Now do the same for virtually any spring-suspension turntable(I know of anyway), and the arm will start jumping around like a 2 year old child with a tantrum...
So, while it is true the SL-1200MkII was introduced in 1979, the physics behind isolation have been well documented decades before that. Isolation is accomplished in part by correct rejection/damping of unwanted resonances. I doubt there is a better table out there for that than the 1200. Look at it like this: if Matsushita forked out the bucks to design the SL-1200MK2 today, I don't think they would have made it any better mechanically. The electronics may improve by integrating all the discrete circuits onto an IC, but the mechanical portion wouldn't change. If the SL-1200 was designed today, my guess is that it would sell for anywhere between $3000 and $4000, factoring in inflation, and other costs. It's amazing how this table "slid under the radar of inflation" and manages to seel for what it does. IMO, it's a gift at the asking prices. It's too bad that audiophiles don't give this table the credit it deserves. I strongly believe most of it is mere snobbism, that they cannot believe a 'DJ' product can outperform an audiophile piece.
In my experience, an SL-1200 Mk2 with a Rega arm, and a good cartridge to match, provides a superb level of "speed", neutrality (especially in the midrange), openness and transparency, all without the mushiness and over-warmth of some belt-drives.
