I'll go with Jim on this one. The first call that I learned to blow properly on was a Mallardtone-5, which I believe actually cost $5.00, jeez, I must be getting old.... I then went on to a couple Olts and tried a bunch of others, but in the early 90's was able to try an Iverson call which belonged to a friend,and have not found anything better. I use the Championship model which has a flat single reed. They were not cheap but worth every penny.Unfortunately they are no longer made and rarely come up on Ebay. I tried a few double reed calls but always found them difficult to blow. I'm sure that some of them are probably fine. Just remember that the air comes from your guts not your cheeks.
Good luck.
