Inexpensive good box call...go with a lynch or primos has some nice ones out. If you're looking for a really nice one then go with a custom call maker..but they can get pricey to get one from one of the big guys
I have a lynch world champion that I have used for the last 19 years,and it has never failed me, but last week I ordered three Ferocious Box Calls. They sounded great. I think I'm still gonna go with old faithful Saturday though.
