I don't know if this is considered a classic or not, but I have the opportunity to buy a Spectrum Comp 90 for $15 dollars. It's roughly 6/10 condition and 4 3/8ths grip. No cracks just really a few heavy nicks here and there and no rash. I think it has a leather grip as well. Is this a good price for this type of racquet? I would like to put it in my tennis room/office on the wall but do not know the value of the racquet.
