Sennheiser 438 Cable Replacements/backups?

hi there! been months since I've been on here and I finally made my first audiophilish purchase on boxing day, 2 pairs of 438 Sennheisers for 50 bucks a pop and I've been loving them ever since and I'm NEVER going back to cheap crap headphone quality, though I had a question, where can I buy both the portable and full length (4ft version and 10 foot versions) replacement cables for these phones? I checked Sennheiser's site (both of them, I'm in Canada and only have paypal for payment method) and there was no section for them in the parts store, I'd like to have a few extras kicking around just in case so does anyone know where I can purchase them fairly cheap? (they're only cables after all) I'm mostly after the 4ft ones for portable use.

links and such are appreciated!

Thanks in advance!

daily bump, really want an answer to this...

daily bump again I REALLY NEED THIS INFORMATION :-(

I also think that this is the main reason I stopped bothering to post here, most of the time no one ever replies and you get completely ignored until your post falls into the thread abyss, I thought these forums were here to HELP people not ignore them all the time (as I've seen 5 or 6 dozen cases of when I was searching for info about various headphones around xmas time, threads with nothing helpful at all in them, people completely ignoring the OP's questions entirely or no one replying period, just like this thread :\ sorry if that seems whiny but it's simply the truth I've seen around here.
