In-Dash CD Changers?

Does anybody know of a good in-dash changer? I have a 2001 base model regular cab with radio/cassette player, and I'd like to avoid installing a changer behind the seat. Is there a stock changer that would work without having to monkey with Passlock codes?

If I end up having to go with an external changer, where and how is a good place to mount it? And what can you tell me about the universal changers that play through the FM radio?

Thanks

could get an mp3 player. you can get usually 12-16 albums on one disc when u convert to mp3 format.

Universal changers aren't that bad. We had a universal with the FM modulator in my wife's old Nissan Quest. Sound quality was ok, but we're talking about a minivan here.
