I saw the price also, and I almost couldn't believe it. 134$ for a CS base pack with only one engine type with the option of adding the others by paying more.  I'm not here to bash or praise, just make an informed decision about buying this product.  Having read here and in some other places it just seems for the price and "potential end price" most buyers are very disappointed.  I would love to add a 767 to my hanger, but from doing research it doesn't look like a I will. 
CS it's your company, and you set your price. I just think as a good show of faith to people that are buying, and have bought your products you should be including all three engine types in the base pack. If then I would consider buying this, and the freighter expansion.  Right now I'm now a hard no.
