Does your pro shop carry previous year's bows? They should have a section of discounted bows that people have sold/traded in for something new.

Check into those, you should be able to pick up an '05 or '06 model for a couple hundred less than a brand new model.

At least go into the shop and start talking to them. Tell them the situation you're in and get all the help from them that you can. Unless they're really swamped or are just jerks like the guys running our shop they should be able to help you figure out everything you'll need. You may not purchase it from them because of financial restraints, but at least you'll have a better idea of what you're looking for and possibly have started to develop a friendship with the folks at the shop.

Show them you're genuinely interested in learning about archery and I think they'll be more willing to lend you a hand when time permits.

Good luck and keep us posted!
