Question About Optimus Electronic Keyboard MD-1600
I was given a musical keyboard with optimus md1600...

I was given a musical keyboard with optimus md1600 on the center, is this a brand or just the model. Who makes it? Yamaha? What's it worth? It seems the left speaker is not sounding right so I am wondering if it worth repairing it before I invest a lot into it. Please help.
