Kevin unlike most of the readers and posters on this thread, including myself; you are in a very unique, and envious position I must say, (probably to the owners of ET 2’s and ET speaker products), to be able to contact Bruce, take the short drive, and see Version 2 of the ET tonearm in action. When you witness and feel, first hand the action of the bearing, you will understand how extraordinary it is, compared to other air bearings.
Regarding those two linked ET tonearms/tables for sale - I myself don’t buy anything unless I perceive it as a deal. Now something can become a deal for me, if I know I can personally sell (easily) part of the package that doesn’t interest me.
Caveat
For someone like yourself, coming from long time experience with only pivot tonearms, it is IMO, important that the person be the personality type to see "OUTSIDE" the Box, and to be able to see, work and play ......"straight".
A straight line is demanded for proper operation, whether we are talking about how the tonearm tracks, or how level it needs to be. 8^0
