There are thousands of credit cards out there. Which one is right for you might not be right for others. While some people are completely against the use of credit cards (see Dave Ramsey), I am not. As long as you are responsible with the card and pay off the balance in full each month, you should never have an issue. The added protection guarantees that many card issuers offer is just one of the benefits. If you are still unsure, check out some great pre-paid credit cards.
Below are a handful of cards I use regularly or recommend. If you do any international travel, I highly suggest you look at the Discover Card options below. They are one of the few card issuers that does not charge international transaction fees. This was a huge bonus when I recently traveled to Central America and when I travel to Europe. I was hesitant at first with how many merchants accepted the card, but found out the majority do.
