This year I got the new Buck Gardner duck call for $40 and it sounds great. It has a real deep rich sound that has done a great job for methis year. The one I havefeatures the Spit Tech Polycarbonate, which guarantees not to stick regardless of how much spit, moisture, or water gets in it.

If you go to his site you can listen to the calls right there on the site.

Good luck!
