Qwestar MVP360A AC Adapter

Question

Hi. I am looking for the adapter that will let me use my Qwestar QK-DVDM1 player in my house rather than just in the car. It's a Qwestar AC/DC Power Switch. MVP360A converts 110V AC into DC 12V and lets you bring QK-DVDM1, MVP360 into your home. Does anyone know where to buy one? I tried discountmobilevideo.com and they have none and can't order any more. Thanks.
