The only real difference that i have found is that the more expensive calls will not stick like the cheaper ones will seems they but more time in design. i have a 25$ call that i love and keep replacing reeds on but can't use it during the later part of the season and end up pulling out the more expensive/better built call they all pretty much can be tuned to sound pretty close to the same. stick with a quality manufacture and you will be fine and like others said practice till you can control the call to sing along with the radio.
