i am thinking of purchasing a inexpensive crossbow, i'm not able to spend more than $150.00 for one. my local shop does not have any used ones but said they could get me the barnett panzer 150lb for that price. my other choice would be a man kung 180lb for $90. with the man kung i would have more money for arrows right away but i know nothing about them. which would be the better deal?, thanks for any help.
