Well, I'll beat some of the others to the punch with my advice, lol. The popular advice around here is usually the best:
1. If this is your first bow, go with something that provides accuracy and shootability over speed. Those speed bows are hard to reign in, especially for a beginner.
2. Determine what bows are in your budget.
3. Shoot as many of them as possible before making a decision.
4. After the purchase and tuning process, PRACTICE,PRACTICE,PRACTICE.
5. When you think you are ready....GO PRACTICE A LITTLE MORE.

That being said, I shoot a Buckmaster Hypertech. Good little bow, not very heavy and didn't put to much of a dent in the wallet.

Good Luck with your decision, purchase, and exploration of the wonderful<img src=icon_smile_wink.gif border=0 align=middle> world of bowhunting.

Those who wish to appear wise among fools, among the wise seem foolish.
