I defer to the others on makers on this forum that make box calls in that price range. I don't exactly know who they are.
Aren't Jerry Zebros pretty reasonable and made in WI?
Some of the other better calls at modest prices I can think of are Yellow Yelper of AR (not all on the website, it's outdated).
Jimmy Nugent, Country Boy Calls, Dry Prong, LA.
Lonnie Sneed, Princeton, WV.
