Depending on how much you know about calling and how much practice you have had with other types of calls is a big part. If you haven't had much experience with calls I would highly recomend going with a long reed goose call over a short reed, they are much easier to blow and sound alot more like a real goose. My recomendation for a easy to blow good call for the money is the Glynn Scobey long reed. It is only about $35-$40 you can check it out at the website http://glynnscobey.com/
This is the type of call I learned on and the call that most of my buddies started on.
Good luck with whatever call it is that you try and remember with any call practice and patience is the key when learning
