Some machines can do an overlock stitch but it's way easier to have a serger.

I recommend, if you want to do serging, buying a nice but not top of your budget model, and then saving up for the serger while you start learning your machine. The Brother recommended above looks nice, I have another Brother model that I love! And if you sew jersey or make quilts, the walking foot is an awesome thing to have! Love mine!
