Samsung DVD-S221 DVD Player
Excellent multiformat playback, good bang for the buck
I bought this DVD player after I took one of my grandmother's VCD's to a store and tried playing them on one DVD player after another.  The VCD was formatted strangely, and only this Samsung DVD player could play it, albeit with some juggling.  (You have to stop playback, then skip two tracks in order to get it to play.)  My guess is that the other DVD players, which could not play this VCD at all, all use the same chipset.  I would highly recommend this DVD player, given the feature set that it comes with.
