Over the first five years I hunted waterfowl, I probably spent $200, or more, on quite a number of crappy $15-$25 duck and goose calls. I settled for a while on Duck Commander calls, which were productive, and on a Grounds Guides Best goose call.
Now I use a Gaston Straight Barrel and Gaston Timber acrylic single reed calls for ducks, and for geese I use an acrylic Zink PC-1 and a Grounds Half Breed. They're all easy to operate and sound pretty good, even with my ham handed technique.
