Craiglists is a great suggestion. I'd say for a better quality 2/1 you would need to pay $650-$750. Most often then not you would be responsable for your electrical, cable and internet. Just be patient and you may find something ok for under $700..If you are clean and respecful of the property and people around, with steady job you may be able to negotiate if you sign a year lease.
Right now, there are numerous options advertised on Craig's List in in the $600s for the type of unit you are describing.
