carlc,
Do not be talked into or out of something; by a salesman who is not intimately familar with crossbows. Too many dealers are just that: SALESMEN!! You should really talk to someone who knows, owns , and shoots crossbows. The fine people on this forum will give you good info, for the most part. You can also talk to one of the knowledgeable dealrs who frequent this forum, like Wyvern.
Get as much info as you can before you buy!!
