Open Question: What is the best credit card for an 18 year old?

Ok before anyone jumps to conclusions about how I probably shouldn't have a credit card and that I am going to spend it on everything and anything, no. I don't plan on doing that. I have money on my debit card for that. I am looking into a credit card to start building credit with little things, like gas. And I was wondering if anyone can tell me a good credit card company I should go with? No rude responses please, not all 18 year olds are irresponsible. Both of my parents have had horrible credit and debt and I never want to end up like them.
