Tere's no such thing as a "good" credit card, they're all evil, don't get one, you don't need one, they destroy peoples' lives. I'm 43 and haven't had one in over 20 years. Get a debit card and only buy what you need and what you can afford. If I've gone this long without one why doesn't anybody need one? Nobody does, it's just a way to get you deeper into the hole.
A credit history is important if you ever want to buy a house, car, etc. try the site creditkarma.com and you can get an accurate credit score, it will also show you which credit cards would be good for someone with your score. I love this site and check it regularly.
