Mintek MDP-5860 5-Inch Portable DVD Player
A Solid Product
I have drug this thing over half the world in the 2 months that I have owned it (Germany, Iraq, Texas) and have had no problems.  I take it to the gym and put it on the treadmill for longer runs.  The sound quality is not good on the speakers, but I use headphones anyway.  The screen does not fold out all the way back, but enough that it can set on the magazine rack of most treadmills/bikes/elliptical machines.  Battery life is short--1 movie only--and charger takes only 110 power.  Buy the extended life battery although it doubles the cost of the machine.
