Toshiba SD-P1600 Portable DVD Player with 7-Inch LCD
You get what you pay for - so get this one!
I started out looking for the $99 - $150 bargains, but after looking at some of these off-brand DVD portable players (with screens even larger than 7\\"), and checking many reviews, I decided to go with a brand I trust.  Since I have a reliable Toshiba 32 inch TV at home (now 5 years old and going strong), I did my homework on the SD-P1600.  I've had it now for about a month, and it works flawlessly.  Picture resolution and quality is important to me.  The Toshiba TFT 7\\" screen display (picture) on the SD-P1600 blew the socks off of the other players I looked at.  It is excellent - and the one I bought is great (no dead pixels) .  The size of this player is perfect for trips - especially if you're traveling with carry-on baggage on planes.  Larger screens translate to significantly larger players to lug around.  Keep that in mind.<br /><br />The only negative are the speakers.  The intensity/volume of the sound is poor - but so are most of the portable players.  This does not detract from the 5 star rating.  When you attach headphones (which is how you will typically use such players) the audio and sound quality is superb.  More than enough volume to satisfy anyone.<br /><br />This is a well-made player with plenty of features.  I bought it for $189 (plus tax) at Target, but you can now get it (special sale) at Amazon for about $170 and free shipping!  Highly recommended!<br /><br />Don't go cheap.  Spend a little more and get this gem.
