Pioneer PDV-LC20 Portable DVD Player
Great player -- Best electronics I've ever bought
I just bought this item.  It's the best piece of electronics I've ever bought.  The whole thing is engineered very well.  For example, instead of one headphone jack, there are two -- so that you and a friend can watch a DVD on a plane without disturbing others.  Another example: unlike many other models, the LC20 can charge it's battery independently of the player -- so if you have a pair of batteries, you can charge both at the same time, or watch using one battery outside while the other one charges.<br />Note also that unlike several other players, this model has the option of buying an extra-long extra battery, for 6.5 hours -- with the battery that comes with the player this is about 10 hours of DVDs.
