I would gladly pay 60$ for a Mirage F1 or any other more complex, combat jet. But this price seems a bit too much for a trainer plane... Besides, in my humble opinion, if you already have the Hawk, there is no point in owning another trainer that does the exact sane thing.
Anyways, I wish you all the best, AvioDev. When you deliver a combat module, I'll be among the first to buy it. :-)
