Honda accord 2007 Aux Input help?

So I got a 2007 Honda Accord SE not too long ago, and I love it. There's only one problem that is really starting to bug me: It doesn't have a standard aux input for my iPod like alot of other cars do. Of course when I was shopping around, that wasn't really a priority since I just wanted a car that ran really well. Anyways I was wondering if there was a cheap way to get an aux input installed? I've been on crutchfield but I'm not sure if I should just buy a new radio that has one.
