Aerosoft's having a sale that includes a few products I've had my eye on, but I'm not sure which would be the best one to get. Out of these, which would you recommend? I'm mainly trying to choose between Antarctica X, Anchorage X, and the Twin Otter. The Twin Otter looks really good, but I don't have any addon scenery, and I've been wanting to start building up my scenery library. What do those of you that own these products think?Thanks,boeing247
