Don't worry about buying a used call, there are quite a number of newly made ones by excellent makers available. Go to reliable local sporting goods store and talk to the duck hunters. The answers you are going to get on are from experenced waterfowl hunters not some clerk in one of the nationwide retailers, not saying that some are not knowledgeable. Nationwide retailer that I might look for advice by phone or e mail is Mack's Prairie Wings from Stuttgard, Ark. Most employees I've dealt with are very knowledgeable as their main emphasis is waterfowl hunting. A good website for waterfowl hunting info is The Refuge.
Above all when you become proficient Do Not Over Call, gotta comeing shut up. I think you'll love waterfowl hunting, been at 60+years and can not get enough off it. By the way I leave my mallard calling to my hunting partners, do good with the other ducks, but not mallards. Right now tuneing my turkey calls.
