These days, DVD players are cheaper than some of the new Hollywood DVD releases. Case in point: the GREEN HOUSE GH-DV100S, on sale around now, has all the basic features - the usual DVD and CD formats, remote control, composite and S-video connectors, and even coaxial digital audio connector - for a mere JPY3980. (Don't look at me, though, if the unit barely makes it to the one-year warranty mark.)
