The Saitek Pro or the standard one?

[Vengeanze]

What's your recommendation between the Saitek X52 Flight System or the X52 Pro Flight System?

The Pro has this SDK and is programmable (?). Is this something I need?

Other differences that I found.

1. Tri-state LEDs (which are also accessible by the SDK)
2. Dual spring centering mechanism - provides incremental stiffness as you move the stick away from centre
3. Dual hall effect sensors for increased accuracy of the stick axes
4. Metal shaft and centering mechanism for increased durability
5. Selected metal parts

BIG difference in price here so if not needed I'd go for the standard.
What's your take?
