I have a TNT version 2.5 (close to III) and it's been nothing but steady over the short while that I've had it. Once it was set up, it remained set up. Currently using the 10.5 arm and an AT-OC9 (anyone have a good cartridge recommendation). I would highly suggest that you consider getting either a Seismic Sink or a Bright Star Rock/Air Mass assembly if you're going the Aries route. It has no suspension and the isolation devices would be a serious asset.
I am also the owner of 2 Well Tempered tables, an HW19 MkIV and an HW19 MkIII. All of these were serious upgrades from my Linn LP12 (talk about set-up problems!).
