Are you talking about the little ones that appeared everywhere just before Christmas for $10 - $40?
These are good novelty fun for indoors and calm conditions, but very basic. I have a cheap one from Daily Deals that my daughter loves watching. Easy to fly and fairly bullet proof.
If you mean the real ones with proper RC units and many controls, then seek out an RC flying club in your area and see if you can go along to a meeting. These are a lot harder to fly and a lot more expensive. They are also non bullet proof and the most expensive part always seems to break when you have a hard or uncontrolled landing. (Some unkind people might call it a crash).
Can you already fly fixed wing RC? If not, going straight to helis could be ambitious.
