RE: how much will a matthews legacy or lx be just the bow by it self.
for a new one you will be looking at 600 plus.
But be honest with yourself if you are in the market for a new bow go and hit as many pro shops as you can and shoot as many different bows as you can.
You never know Mathews just might not be the bow for you.
There are a lot of good bow companies out there and they all make some mighty good bows.
Make your choice on what bow feels right for you and dont buy the first one you shoot. Like I said shoot a lot of different ones make a short list and go shoot them again then make your choice.
Good luck in your endevours
