Turbine Engine Costs

[CRAN]

Guys,

Do any of our colleagues in the maintenance or operations field have a feel for the unit cost of the following engines?

Rolls Royce RR300

Turbomeca Arrius 2K1

PWC PW206B2

We're working on a CHP application for an offshore project and are wondering if we can use an aero-derivative engine (for this application in the 300-500hp class, size & weight much more important than cost.)

Thanks,
CRAN
