I have the gc300 and like it. I'm really new to predator hunting so I've only had about 4 or 5 stands, only called a fox in so far. For the price ($60-70) it's really nice and is definitely an alternative to the Foxpro Kings. The only complaint I have is the the general "coyote howl" sounds really weird and off to me, however the individual female and male howls sound fine. I look forward to using it a lot this winter.
