That dual throttle stick looks like a good idea (2 throttles) but the layout and implementation sucks! I mean look at it! You'd have to hunch over it with your wrist cocked at an odd angle to manipulate the throttles WHILE holding the stick! Forget about throttling up or down while actually moving your control stick around. The clunky base with uncomfortable buttons doesn't sell me either, and the ugly, simple, stick button layout leaves a LOT to be desired.
2 throttles or not, I don't think I'll ever use that stick.
As for the MS Prec pro. I have one (analog), and I'll tell you this: They're not perfect. If you just want this stick, go for it. If you eventually want to start mixing and matching various input devices, go with something else. Analog MS Prec Pro won't work with analog rudders. In fact I don't know if it works with USB ones either (not sure, heard some comment that was ambiguous in nature).
So keep in mind that, while it's good for not, it may cause you troubles later.
