Coby TF-DVD7100 Portable DVD Player
Does what it is supposed to do.
Bought this from here, got it promptly, and have used it for probably 20 hours over the past month (including putting it through a six hour burn-in period on the first day).  Plays all of my store-bought DVDs (including Pixar titles), picture is nice for an inexpensive system, audio is a little low, but fine for watching in bed.  Lots of fun in a small, inexpensive package.
