I hunted with Gadget Bob's snow crow pro and bought one immediately when I got home.
Customized with 2 sp55 speakers, extra on off speaker switches, external off switch, and able to hook 4 more external speakers on it. Sure it will run a guy around 1400 bucks but man is it SWEET.
My go to caller now. The Krack just sits and collects dust now. I do take out the Ghetto (Prairie) Blaster every now and then.
