I am looking to purchase as crossbow to hunt whitetail deer with. I have never owned or shot a crossbow but have been hunting with a rifle for 40 plus years and taken many a deer. I was wondering what brands I should consider? I shoot lefty and am wondering if that makes any difference in a crossbow. Also, I see on Ebay there are many different types and even when it comes to sights and scopes, etc. I only know one other person who has one so all opinions are welcomed!
