I don't need the photos feature because I'm pretty certain my niece does not have a digital camera. But I'm realizing from what everyone has posted that $200 dollars is not the mid range that I thought it was. I believe I will need to up my price range by at least $100.
Signal to noise ratio? Something else I know nothing about.

Signal-to-noise ratio is a term which describes the output audio quality. Higher this ratio, better is the audio quality.
More signal, less noise = higher S/N ratio.
