My most prized guitar is a Martin OM28-V that I just bought about 2 months ago. A few weeks after I bought it the owner of the music store called and said that someone else had been close to buying it before I did and now was offering a "premium" to buy it from me because he remembered the one that I bought sounding better than the next one the store got. So I went down and played them both and told the owner, "He's right - mine does sound better and I'm keeping it."
