I took one of the 0% deals out once and it worked great. I needed about 1500 to finish a shop at a new house as I'd spent everything saved for the project. Took out the card, finished the shop, paid that sucker off as soon as I had it, and then cut it up and canceled the account.
Great for times of need when you are in a bind IF you are very good at paying them off in full on time. Needs and wants are two different games, I'd personally wait till I had the money saved for a gun purchase.
As another poster mentioned, don't have a late payment or no payment one month. If you don't make the minimum payment each month, the zero is gone and they'd jack it up over 20% plus add fees. Too many people get screwed by CC Cos, they aint for everyone.
