I need to find a publication that has all the necessary info for someone to compare and choose the right aircraft for the job.
Turboprop and jet.
Worldrover,
BCA (Business and Commercial Aviation) puts out an issue once a year comparing most new and out of production aircraft, both turbo prop and jets. Its just a brief overview of the airplanes but it will help narrow your search. After you pick out a few possible candidates Conklin de Decker (sp) has a comparison tool that will give a more detailed cost analysis.
