My factory radio died so I decided to go aftermarket. I got a Sony CDXF-5700 at Circuit City. Here are the details from Sony:

Circuit City did the install for free since the stereo was over $99. I decided on this one because it plays CDR/CDRW/MP3 and it has a sub out. I was very happy with the installation and they also have a price match guarantee, so a week later when it went on sale I got $23 back. So originally it cost $259 including tax and parts and then $236 with the cash back. It makes my factory speakers sound even better. I talked to some friends who have had Sony stereos for a while and they were pleased with them as well. If you want to know what it looks like installed I can find my digital camera and send you a picture.
