Based upon what I have read and heard from others, the T3F is not a desirable arm, at least in part due to reliability or staying set up correctly. For $4750 you can do better, in my opinion. The Air Tangent is a really good arm, although about twice the price. I do not care for the Clearaudio/Souther arms with their very short cantilevers which are very susceptible to warps and critical of VTA settings, and they are not air bearing type which I prefer.
