what i would recomend is buying a package kit. Then when you leave the bow shop you will be shooting and the pro shop will have you tuned up and ready to go. then as you have the extra cash you can upgrade your set up.
I recomend this because when the time comes that you want a new bow you can take your good stuff off and put the package stuff back on and sell the bow ready to shoot. Buy a new bow put all the upgraded equipment on it and you will be happening.
Just my thoughts on the subject.
