As for an electronic caller, the FoxPro Wildfire is a fantastic value. A $200 pricetag might seem steep, but I honestly would NOT recommend any caller below that price point. You WILL be disappointed by them (Flextone, cheaper Primos, cheap Johnny Stewart "Attractor", etc). I'd be hard pressed to recommend any other caller besides the Wildfire at $200 either, the Primos Turbo Dogg is a decent caller, but the remote range isn't nearly as good as the Wildfire, and Primos customer service is a joke. If the Turbo Dogg were $125, then maybe I'd recommend it as "ok", but at the same price as the Wildfire, I HIGHLY recommend you avoid the headaches and get the FoxPro Wildfire. Drives me nuts that the Turbo Dogg doesn't have a good way to carry it either.
