One of the noteworthy ones around making Neil Cost looking calls. Apparently makes a nice call. A fair number of folks make Neil Cost look a like's. However I might suggest a box call or boat paddle (or both) from Lamar Williams in Florida, a true student of Neil Cost, who spent the time studying under him. If you order you'll have to wait, unless you pick one up on Ebay, which will run you about double. But you don't have to wait a year or three...lol.
Another thought...pick up an old 1958 Lynch World Champion call with the Birmingham, Ala. address on it, an early one. Probably $100-$200 on Ebay. Make sure it says Birmingham on it. Will hold it's value. Just about as good as you can get in a box call, for less than a custom. For lots of Gobblers over the past 50 years or so it was the last thing they ever heard. The newer ones have a different address on it...Liberty, Miss, etc. Sound good, but not that collectable and aged to perfection.
