I'll second and third for Billly Buice...but then again, I'm a little biased
Best thing to do is visit call makers of you can or visit a few shows and play a few. Not all sound alike and most all "run" differently. Some call soft, some louder, some are very pretty and sound like you're pulling air through a straw stuck in a coffee cup. They're kinda like shoes, try em on before you but cuz they're all gonna fit differently.
That said, I'm really partial to my Osage Trumpet from dad
