Experience w/ Trans-Fi Auio Terminator Tone Arm?

How many of you have the Trans-Fi Auio Terminator Air Bearing linear Tone Arm? Or the older Trans-Fi Evolution Tonearm. What is your experience with this arm, how satisfied are you with this arm, and how does it compare with other tonearms you have tried?

I am seriously thinking of getting the Terminator for my VPI Super Scoutmaster with Rim Drive, but have no experience with linear tone arms. I have found just one person on Audiogon who has this arm and loves it. This fact is somewhat confusing to me, since if the arm is so great, as some people say it is, you would think more people on Audiogon would have it or at least tried it out.
Thanks,
