Stick the multi changer on ebay and use the extra money to buy a better HU 
i totally agree, changers are useless now when u consider somthing like the alpine 9850ri with full speed ipod control,
prices range from £199.99-£229.99 fitted. u could then keep ur entire music collection hidden neatly away while u control every function of ur ipod through the h/unit and it will charge the ipod as well,
awsome bit of kit for buget money!
