What I would do if I were you, research all you can on the different options available to you. Read articles posted on bow websites about buying a bow and the different options. At that point, you may price some bows online and then make a tentative budget.

Then go to a local shop and take a look at what they have.
1) how it holds/feels in your hand
2)consider the weight of the bow
3) how smooth the draw is
4) how it shoots
5) how fast it shoots
6) how loud it is

consider these and don't let anybody pressure you. Go with what feels right
