Yeh - I believe I just have really ****ty luck when it comes to buying things - most of the stuff I buy has to go back at least once, and its not just my imagination... my girlfriend is astounded, she now gets me to get the store to unpack and test instore to save multiple trips. Things like stuck/dead pixels, my previous home theatre had a dropped speaker in the box, and it didn't work work with PS3 over HDMI (a known problem apparently).
Even buying a house proved complicated - and I would of returned it if possible
Fortunately, my luck gets returned in other areas of my life
