Second VPI's HW-19 suggestion. The Mk.2 version is different from the Mk.3 only in having a layer of steel rather than stainless steel bonded to the bottom of the MDF plinth. Replace the stock spring suspension with something better (SIMS Navcom Silencers are popular, as are Herbies Audio Labs Tenderfeet) for an upgrade.
Perhaps the best used VPI value is the Aries 1, which is a mini-TNT without that table's suspension (use Townshend Audio Seismic Pods in place of the Aries' stock cone feet); an excellent platter and bearing (the exact same as found on the TNT-3/4), and a separate 16lb. motor pod.
