I got this collectable off eBay a few years ago, http://i53.tinypic.com/3354bat.jpg, as a toy when i was a kid, I was stumbling around the internet and found this, http://www.atomicmall.com/view.php?id=1141337, a similar item going for a good chunk of change. This one is far nicer however mine is only a plastic model with working lights and sounds but i don’t know if it’s even worth anything. Is it worth saving and protecting?

The name of the Star Trek Voyager Season 7 episode is called: Human Error. The episode begins with the character, Seven playing a classical piano piece that is very pretty and sort of dark/mysterious. Please help me by giving the name of the composer and piano piece. Thank you.
