Several years ago someone gave me an Epiphone PR-715-N, serial number 97805. The man who gave the guitar to me said that it was "very nice". I don't play it and want to sell it but I have searched everywhere and cannot find any info on this model. I was thinking of getting it appraised... could anyone tell me if this model is a cheapie or if it is worth my time and effort to have it checked out. Thanks!
