If you live in Canada, you can always try buying within Canada. Saves on import/customs fee even though you can't save on taxes. Depending how they're declared you can be in for a huge surprise when they arrive at your door. Also depending on the postal service used.
The straight cable version is regular price.
The silver LE also.
The black version is regular price.
Prices are pretty similar, and I don't know how much shipping could be. Also ends pretty soon (like today and tomorrow?!) with less choices in colors for the same price.
Well, just an option.
As for which of the two, unfortunately I've own neither and cannot really give a sound judgement.
**EDIT** Let me add that I've never worn the M80's so I don't have personal opinions on it's comfort and sound.
**EDIT2** I'm an idiot and linked the same URL twice. Fixed that.
