Captain Sim has a mixed reputation, but having said this, many of their products are still exemplary with immaculate detailing and superb animations and features, and with 100's of liveries available for each of them.
Do be aware that you need to buy the base pack of the model you'd like, plus optional product add-ons and variants. Also, note that their later models (L1011 and B777) have separate FSX and P3D editions.
Whichever way you look at it, these machines are absolute bargains for $9.99!
