I've got an older RED STAR MP3-CD car radio that has been the cheapest available here when I bought it too (139 € half a year ago) - The handling is a somehow strange, but no mp3 compatibility problems so far (--alt preset standard works fine, audiobooks @ 64kbps too) and the sound is good enough for me when driving.
