Guys what is the best payware add-on for FS2004 in planes like 747,777 and does anyone have cargo pilot yet???

For the 747 it's PMDG ( http://www.precisionmanuals.com ) hands down.For the 777 it's PSS ( I won't link them because I think their work is garbage but to each their own ) only due to lack of options.

Without a doubt the PMDG 747 is the best 747 package you can purchase, in my opinion. There is also a good 777 simulation by pss. It is not as good as the pmdg offering in terms of simulated systems and overall program stability, but it is by no means garbage.http://www.phoenix-simulation.co.uk/.
