Artar, I too have long been considering a TT upgrade, and the Teres has been on/at the top of my short list since TWL pointed it out in a thread I started here some time ago. (I, however, will probably spring for the 150 or 160 model for reasons of budget, and use it with my OL-modded RB-250. I'm almost there...)
Among the other 'tables on your list, I auditioned (and was very impressed by) the Gyro SE. The standard VPI Scout didn't impress me as much (at least in the context of the dealer system I heard it in, which was far less expensive than the one in which I heard the Gyro SE). I haven't yet heard the Scoutmaster.
I'm looking forward to "part two" of your post, and to hearing what your thoughts are once you have the 245 up and running.
