First, check your local college campuses for abandoned bikes. Next, look for used bikes in good condition. If the landscape is mostly flat, then a nice singlespeed would be hard to beat if the previous options aren't available.
*If you're not familiar with singlespeeds, then stick with multi-speeds. Perhaps even a 3-speed would be a better option for you.
** Sometimes campus police can inform you about abandoned bike sales...
