Okay, so I am a beginner for the piano and i have been bugging my parents for a keyboard for a while. So i looked around and i saw those two and i was just wondering which one everyone thought was better? The EZ 200 is really cool because of those lights thing and the PSR E313 is cool because it just is. It would really be helpful to get peoples opinion. Thanks. Oh and by the way I was also wondering what Factory B Stock stands for? It would be really helpful. Thanks Again.
