I bought one at either Walmart or Mills Fleet farm last year, and it seemed to work pretty well. However, before you go spend your $ on one, try this. Take two quarters, hold them perpendicular to each other, and rub the ridged edges together. It will take some practice to get it perfected, but once you do it will sound much better than a store bought call. Plus it only costs 50 and you still get to spend it after you're done hunting.
