Yes, buying karaoke on line is the cheapest way. Just be careful when buying karaoke gear online if you ever have to return an item. Look at the online stores return policy, some will charge a 25% re-stock fee or exchange only. For me
www.zzsounds.com is the best for price, delivery time and return policy. They don't really have karaoke discs though. For karaoke discs (CD-G, SCD-G)
www.karaokeproshop.com www.karaoke.com
www.doowop.com www.cheapkaraoke.com sells the CAVS CDG, SCDG & MP3-G (type) player.
