The standard speed3 CD changer does not play MP3s. Only the replacement one does.I might be interested eventually... I have virtually no interest in a CD player of any kind. I do not own a Speed3 yet though. If I buy one at all it'll probably be somewhere in the neighborhood of a couple weeks.
I'll have to look into the logistics of putting another deck in there as well...
If Rotus8's price is right: $500 for a replacement without waiting and without hassle might be worth it IMO.
Keep me in mind.
