FM broadcast signals are bandpassed so everything above 15 Khz is clipped out of the audio signal. With this in mind no FM station will reach CD quality so spending as little as you need to (assuming the rest of your gear and your ears are up to the task) may be the best bet.
A $60 tuner and freight should be within your target. There are a few options (http://cls.audiogon.com/cgi-bin/cls.pl?misctunr&1107142572) listed at audiogon and at that price point you will get a FM signal through your speakers.
Do not be too upset if the sound is not great but it will be better than what you get from a boom box or your car stereo considering the wind and traffic noise.
