Funny thing, when I took my first deer that I shot with a bow, I shot with a used Bear Whitetail Hunter that I paid 50 bucks for in 1985. I took a turkey 3 weeks ago with a Matthews Z7, that between it and all the crap I have hanging on it, I probably have up at least a grand invested. You know what? The thrill is the same. The stalk, the calling, the moving so slowly it takes a full minute to draw the bow, all the while your heart is thundering in your ears so loud you are afraid that big buck or tom can hear it, as you wait for the perfect shot, your mouth is dry, you are holding your breath. That thrill, you can't put a price on it.
So in the begining don't worry about cost, shoot what you can afford.
I'm your Huckleberry!
