Hey Taurus,
Either a box or slate call would be a good call to start with. Don't worry about the price of any particular call.
Also, don't fret if your local store doesn't have the latest "better-than-lead-absolute-turkey-smoking-magnum-shotgun-shell" They work, and I like using 1 or 2 brands, BUT they're not deal breakers.
My first bird was done in by a 2 3/4" lead shot turkey shell that doesn't sound impressive compared to discussions about more modern 3" or 3.5" head smashers. Find a shell that patterns well out of your gun and go with it.
I'm not sure if there's a final word on turkey hunting, but I'll post this so it doesn't get forgotten....Sometimes they really do come in just like on TV. Other times (most times?) they're a bit more cautious.
BUT...when it does happen, you'll never listen to a turkey gobble the same way again.
Good luck this spring. Go bust a big one!
