Turntable suggestions for a shaky wooden floor

I'm using a Rega RP1 and had a significant rumble with even the softest volumes.  I used a cutting board with Sorbothane hemispheric feet and now can listen to music at a pleasant listening level.  

I'd like to step up to a nicer turntable but I've heard some are much better with rumble than others.  I would like to spend $750-1500 for the TT and cartridge.

So far I'm thinking of getting a Technics SL-1200MK7.  Any suggestions on something better or more stable?

Thanks for your time
