Yeah, FM Mod Changers are great. Great, that is, if you like crappy sound.

No offense to anyone who uses them and likes them, BUT, I've had both, and heard many of each, and there's no comparison.

Best value out there is the JVC 12 disc changer with 35x4 cassette head unit. I paid $212 for mine from U-bid -- they have them on there all the time. Strangely, it's the best sounding head unit I've had in my car (and I've had Pioneer 40x4, Sony 40x4, before this one) and by far the cheapest. Best display, too, really easy to read (even in bright sunlight).
