RE: compound bow for beginner?
As new as you are,you really wouldn't know what would fit you.That is the MOST important thing with a bow.Getting one that fits.
You need to visit a bow shop and talk to them about getting a used bow that FITS.They might have one in stock or give them your name.They have customers all the time that are looking to get rid of their old bow.They should take it on trade or let them get in touch with you directly.
Be patient,deal with a reputable dealer and you should be able to get one in your price range and one that fits.
