Since your question was about pot calls I will comment on them. If money is an issue I would get a good slate call and a few different types of strikers as different woods can give a variance in sounds. I had a triple threat type call a few years ago and would agree that the surfaces are too small better to get one good full size pot. Also with the entire surface you can move around the call surface and may find that a certain area on the call gives a better more consistent sound. Also if you look in the stickies you will find a very good tutorial by Adrian Hare on conditioning your calls ! There is also a good guide to pot calls by SwampCollie unfortunately neither of them come to this site much anymore and I wonder to myself why is that!
