Hi! My wife would like a karaoke system for when we entertain. Didn't know the first thing about them, but after a little research today I guess I can say I understand the basics. Anyone have any recommendations? I see you can get some systems pre-loaded with lots of Chinese songs. Are these worth the uplifted price, versus building your own library? Any systems just perfect for a night of Chinese/American karaoke? Any advice would be helpful. Thanks!
