Hey
for me it looks like a SS-36 Silverstar. That?s the base model for silverstars, not high end. Still a good guitar.
Chances are slim that it?s a SS-48 if it has the schaller-style tuners. (would need to see a picture of the back of the headstock to confirm)
SS-80 or SS-85 would be high end.
For the price I don?t know. If it?s an original Tokai case that would be a plus. Try to find out what they sell for on ebay and you?ll get an idea what it?s worth.
