Don't feel bad. Someone from college bought my QuietComfort 15 pretty cheap when I got the 35. I found it odd that he'd buy it as it's pricey there (Brazil), and tried to convince him not to (as he wasn't rich or even working regularly). He told me not to worry and asked to pay in installments. I made the mistake of accepting his offer, and he practically vanished after paying about 50 USD for it (I sold it for about 130 USD). I am someone who he could ask a referral. Instead, now he has a recommendation against him.
