I don't have a lot to spend, but was wondering what would be a minimum for my first crossbow. It seems like a perfect SHTF weapon. But I don't know anything about them. What are decent (not top of the line, just decent) brand names? How many bolts? Pounds? As an idea, I ran across this one at Amazon and read the reviews which were not bad. I know it's probably cheap, but could it be decent for a beginner? And honestly, I don't want to hear "Save your pennies and buy this $2000 unit, you won't regret it" type of answer. Thanks for anything.
