There are a few that look ok - and hey for a few hundred bucks if it gets you through until you get back to Canada that is worth it. FWIW I have had issues with companies shipping computers out of the US/Canada to foreign countries - not saying its still that way but in the past it was...

Yes - I've also found them in places in Akihabara - but you have to look hard - they are there - but not typically on the main street leaving the train station...
