I'm planning on adding MP3 integration to my M6s before the end of the year, I like 2 products from Audiolink at therpmstore.com, the usb mp3 player and the ipod integrator.

I'm wondering if anyone has used any of the products and what your thoughts on them are? I like the usb mp3 player but not sure if I can attach a portable hard drive to it, if I can't I would rather get the ipod integrator.

Thanks in advance.
