LOVE to sing? This personal karaoke machine enables you to belt out your favorite tunes anywhere. The "Hi-kara" karaoke machine, by Takara Tomy, is a 7cm cube that works like a real machine. Once the singer selects a song, which can be downloaded off the Internet or played from special music cartridges, the lyrics appear on a 2.4-inch display. The machine comes with headphones and speakers. It will go on sale in October for about $100.
