K-mart is blowing out their PSone stuff. The 5" LCD screen is $13 - the box maybe marked otherwise, but they are ringing up $13 everywhere. Also, the Sony PSone car power adaptors are ringing up $4.
These are the genuine Sony items, not the knockoffs.

all you need is a mini > rca connecter to give it an rca input
