There are many, many good hand calls. Sceery, Red Desert, Critt'r Call, Tweety's ect.. I always buy open reed calls which can produce sounds from a rabbit distress to howls to hurt pup yips. Open reeds also have the benefit of not freezing up in -30.
Ive owned a number of FoxPro's in the past and they are nice but definetly not a must have if you know how to use a hand call properly.
