Janos,
An alternative might be the PMDG models, wich i think are better as the PSS ones, even the new 777 by Phoenix isn't as beautifull as the 747 QotS from PMDG. The only PP problem with the 747 is the penalty for not switching on the rotating beacon, altough it's switched on, this is not the case for the 737-800, a fantastic plane as well.
greets Niels
