Spud,
I can understand your concern for saving your hard earned, however, the Tongass Fjords scenery is well worth any penny and not just because there are some AI aircraft in there. The scenery is incredible with the villages, small townships, floatplane bases, etc. all modeled with custom libraries only found in Tongass Fjords.
It picks up right where Misty's stops at and It's worth it trust me you won't be disappointed. With Holger planning on releasing a "Glacier Bay" update for FSX, you'll have uninterrupted floatplane heaven from Yakutat to Southern Oregon.
