Okay, I have a Canon Rebel XTi. I'm a poor college student and currently only have an 18-55mm lens. A ton of my pictures usually come out blurry It bums me out.
When they don't come out blurry, they look like this

but i'm still not happy.
What's a reasonably priced lens that will get the job done?
