Gemini Jets doesn't even have an MD
-80 mold. He meant to say Dragon wings.
There have been 4 versions of the AA
md-80 made by Dragon
Chrome version...extremely rare and was bought up really quick when first released
Polished version...same as above
/TWA chrome version...limited run and just about as rare as the 2 above
White version...currently out now and priced under $20
If you are interested in the first 3 my suggestion is to check ebay often. I would also check the model trader sections of the following forums...diecastaircraft.com, wings900.com, airlinebuzz.com
Sometimes collectors don't realize how much these planes are worth or are in need to get rid of them quick so they are reasonably priced.
I myself have the first 3 models listed and bought them for under $35 each all second hand within the past year and a half.
