Collecting decoys requires the same research as collecting guns. Do a Google search and you'll find dealers like RJG on the internet -
http://www.rjgantiques.com/ and auction houses like Guyette & Schmidt -
http://www.guyetteandschmidt.com/There are lots of books published on different makers and regional styles too. Take a look at Amazon and you'll find plenty of research material. Bottom line is you can spend as much or more for a nice decoy as any fine double gun you'll ever own no matter how deep (or shallow) your wallet.
