Does it matter what kind of baby carrier I get?

Right now I have the sling but Brielle's about to outgrow it and I wanted to get her a carrier where she can sit up on my chest. I'm kind of strapped on money but if I were to get one of the cheap $30 ones, would it give me back pain? I don't want to waste the money on something cheap if I wont wear it because it hurts to so I guess I'm asking about ya'll's experience with the cheaper baby carriers.
