I need a Good Secure Online Backup

I've decided I need to get a secure online backup. I mean you never know when your computer is going to crash. It worries me sometimes so I decided to take the plunge. I like knowing that my info is safe and if I need it for upload if something happens to my computer I can do it. Who actually has the best prices though? It is kind of a toss up I think, but if anyone has a suggestion I'm all ears.
