Hey all.  I am considering purchasing some FSD planes for FS9.  I was wondering how they are?  I have the Wilco/Feelthere, Aeroworx, Eagle Soft/Digital Aviation, Carendo and Flight One planes. Which of the above mentoined manufactures do they compare to.  I am not a big fan of Flight One planes. I think Flight one lacks in their system simulation/modeling.   I do love the Digital Aviation Cheyenne and Aeroworx King Air and the Eaglsoft Twin Comanchee.  I am considering the Avanti, Cessna 337, Navajo, and maybe the Cheyenne 400. 
Any info on these would be great. 

Thanks.
Joe
