Karaoke Machine with Monitor

I've already bought two of these machines and the sound is really good. I gave one to my dad for his birthday, and I bought another one to take to a party at my friends house. They simply loved it and we had a lot of fun with it. The only thing that this machine lacks to make it perfect is a key change button where you change the music to your own tone of voice...but oh well, that's kind of minimal...With practice the voice gets better, doesn't it? Also, I bought it at Target for $99.99 :)
