There are lots of great bows on the market. Starting out, I'd go cheap. You don't yet know what your preferances are, or what weight(s) you will want to shoot.
The Samick Sage or Journey are both great bows at a very reasonable price.
I'd also invest in the video "Masters of the Barebow, Volume III". Two World Champion archers giving easy to follow instructions--it can take years off the learning curve. You can get it at
www.safarituff.com or 3 Rivers Archery.
Good luck!
