Axion AXN-6042 4.2-Inch Wide Screen TFT LVD DVDman Player
I have this ultra portable DVD and LOVE it.
This unit is so portable yet has a big 4.2\\" WS TFT LCD screen.  It fits into my breifcase and packpack nicely.  The battery run time is about 2 hours.  It comes with car cord and ac adaptor to recharging.  The unit is well made but the speaker is a bit small.  But i use my earphones and that is not a problem.  I can't leave home without it.
