I am a new bowhunter and I would like to upgrade my bow to a newer model. Does anyone know where I can find some good not as expensive bows, or where I can find good used ones for fairly cheap?

Ebay.com They have about any bow you could want.......fishon

What bow are you shooting now?

If you know how to tune your own bow or know a pro shop that will tune a bow you bought elsewhere for you, than ebay or any place will be fine.

I would reccomend buying one from a pro shop, they will set the bow up for you, there are an awful lot of reasonably priced good bows out there, I just got a new one myself, a Browning Ambush, it fits me to a tee and shoots great. Find a bow that feels good to you, you will always shoot a comfortable bow better than any other bow on the market.

I shoot and old hoyt rebel xt right now. On ebay if the draw lengths arent right for me can that be switched?

Yes on most bows you can take them to a bow Pro shop to be fixed up just right for your needs

are there any sites on the net that sell bows besides ebay?
