I did a quick search and this is what I came up with.

http://www.hobbiesr.com/126.htm Shows the plane kit for 64.99

http://www.airlandhobbies.com/p-3650...rainer-40.aspx
Shows WING KIT $27.99

http://www.happyhobby.com/hobb_html/duraplane.htm
This place shows the plane and a wing kit but no price

I hope this helps.
