I have not yet to spend over $20 on a call yet but i have tried alot of the cheaper ones i must say. I seem to perfer the all wood calls. it seems that they put a better sound out than the plastic ones. I have noticed that the ones on crowmart are sculpted very nice and have a plastic mouth piece but im sure they sound better than the store bought ones. Anyways, my favorite so far, that i have bought 2 of them because it has froze on me in the field already and frustrated me is the Penns Woods Crow Call. $5 and i think almost the cheapest I have bought.
I will purchase a nice one from crowmart once I believe I am strong enough on the hand call to deserve to spend more than 20 on a call.
Gibson or Mincey.. tough to beat. Both are made to exacting dimensions, quality control is excellent and both are easily tuned. I cannot say that for the mass produced calls.. Both Gibson and Mincey are available should you have a question about their calls. Good service is a good thing these days.
