Hunter, Not sure where you are located, but if you could wait a while, I'd recommend getting to a local model show and swap meet to see if you could grab one of those old Testors O-2s. I see them all the time, and grabbed my copy just that way. I'm not expecting to hit a show until this Fall, but if interested, I'd be willing to check for you, and I'll bet some of the other guys on the Forum might be willing to help you find one of those. Just let us know what you are willing to pay, and maybe it will work out. Good luck. Can't believe $40 for that kit.
John
