The 1.07 can be brought up to 1.09 spec for very little money, its just a chip change, mine was a 1.05 when I got it but MA Developments supplied me with an upgrade chip for it to take it to 1.09, although I am not sure if they would be willing to help with a "grey import" one or not.

The 1.09 is awesome, its got built in osciliscopes for seeing the crank and cam sensors, and has traction control and launch control.
