Daewoo DVG-9200N Progressive Scan DVD Player
Best DVD player under $100, and for only $40 :)
I bought this for my mother in law in Brazil.  Her city uses 120v, so no issue about power.  Her TV is also mono, and no trouble in the menus to make the DVD player do Mono (if you want).  The region free hack worked great.  Just open the tray, press 1,3,5,7,0 (slowly) on the remote, and you have a region free DVD player.  It withstood the trip in my suitcase fine, and I find it stylish and easy to use.  I can't recommend it more.  Hope you enjoy yours.
