I am in a similiar situation as you. I got interested in bowhunting, took a bowhunter safety course and bought a bow all in the lastthreemonths. Now I am going on my first bowhunt for deer this weekend.
I went to my local archery shop and I talked with the owner about what I wanted and what I wanted to spend. So for a little over $400 I was fully outfitted with a great bow. He put me on to the Misson bows that are made by Matthews,

After a few weeks of practice, talking with the shop owners, and reading the forums (here & AT) I have become very proficient with my bow. I have already killed a turkey and I'm excited about my hunt this weekend.
Good luck and most of all have fun.
