Linear Tracking Turntables

I currently have a Yamaha PX-3 linear tracking turntable, and it was working beatifully until I damaged the tonearm transport. (don't ask). I'm impressed with the performance I got out of it until I damaged it. I'll probably get another one from Ebay, but I wanted to know if anyone had any experience with these other linear tracking turntables that can fit standard mount carts: the Revox BX791 and 795 series, the Mitsubishi vertican turntables, and the Pionner/Phase Linear models. Which of these has the best linear arm?
