What is the cost of the Mirage 2000 series?

Taiwanese sources states that the 60 M2000-5 deal in the late 90s had the aircraft at $42-43 million per plane and there was a scandal over the costs..

From UAE sources, the 33 Mirage 2000-9 deal for 1 billion would put it at $33 million per plane

while Srbin states its as high as 70!

it’s a very wide ranging cost for airplane.. the UAE costs appears to not include spares etc.. as other sources say its 3.2 billion, which would make it 106billion per plane!
