well, my name is dave z. i always happen to find myself at church sales and find collectibles. this time i need to get rid of the stuff i have now due to a new baby comming(#3). at any rate, my last find netted me nine unbuilt models. two are cars (plastic), and the other seven are planes. three are balsa wood, and 4 are plastic. i have an idea what they are all worth except one. can't seem to find it anywhere on the net. it is a sterling "beginners ringmaster", i have spent far to many hours on the net trying to find its value and can't find it. so i guess what i am looking for is some direction as to where i can get a fair market value for this plane. the kit number on the box is S-30, made in philadelphia pa, with no date on it. any help will be far more than appreciated. one plane that came close to the look and model number sold on ebay for $144.00. if i can get that for it i could afford the reusable diapers the wife wants to use instead of spending nearly $100 a month for disposable ones. thanks
