Stoop, you have to find out your draw length. Just take out a tape measure and pinch it between your thumb and pointer finger on your left hand. Pull the other part of the tape measure back with your right hand and anchor it to the right corner of your mouth. That is your draw length. At 5'8" and average length arms, you probably have a draw length of around 26-26.5 inches.

Once you have that, you can order a bow. Do not worry about spending $500+ dollars on a bow. If you have the money and want to, by all means go for it. If not, you can order a good bow for $200-$300. I bought my Reflex Excursion off E-bay 5 seasons ago for under $200 brand new. It has killed deer just like any other bow.

Measure your draw length first, then come back on here and tell us. I would suggest pulling between #50-#60 pounds on your first bow.
