the best source of info is "Conklin & de Decker Aircraft Cost & Performance Reports"; conklindd.com.
It is very comprhensive and accurate,you can purchase the cost & perf. report on-line about the acft you are interested in or even obtain multiple airplanes comparison reports; and receive it on your e-mail almost instantaneously.
Note: Take the salaries with a grain of salt,figures are based on the 2007 NBAA and so they might not be that realistic; you might want to consider to purchase the `08 NBAA Survey separately.
Good luck.
