A very good and inexpensive call you can get at Wal-mart during season is the Haydel DR-85. It is the call I learned on and is still the call I use the most. I have never tried a call that was easier that this one. I think I gave around 10 or 15 bucks for it. Another inexpensive call is called a 6 in 1 whistle. I do not remember what brand I have. I use it mostly for widgeon. If you here a " who...we...who who...who who...we...who" you can hit the whistle and it will almost always turn them around and bring' em down.
