You could also try a search on e-Bay UK and even e-Bay USA if you know what you want.

Best advice I could give would be to get a Midi-Karaoke DVD player from Philippines.

These machines play DVD’s with Midi-Karaoke plus plays nearly all other DVD’s & CD’s,
they come with remote control and song book plus mic (not a good mic!) additionally you have a choice of 5 different video backgrounds which can be switched from the remote at any time.
The biggest attraction has got to be that the included DVD comes with over 50,000 songs plus MTV videos. All the very latest songs.
Total package for me was P1200

Worth thinking about
