Wow 'skulls, that DOES make one feel terrible for the poor guy who's ex took her spite out on what was, I'm sure, his beloved collection! It makes me think of the similar scene in the film HIGH FIDELITY. Only in that case it was rare, vintage vinyl.

All I can say is, that whenever your conscience bothers you about how you came about those nice addituiions to your collection, try to imagine the previous owner as having DESERVED his exe's anger. For your own feeling's sake, think of him as an abusive lout or some such thing. That's what I'd do anyhow.
