Anybody brave/crazy enough to take a flyer on one of these:
Class 6 should be fast enough for flac (not sure bout hi-res), but amazon.jp also has class 10 listed as well.
If you click the specification tab on the microdia link they do have 128gb listed so it might be legit. Unfortunately by the time I get it to Canada shipping and taxes would drive the price high enough that I wouldn't want to risk it.
The card you linked to seems to be a class 10, the text wrongly states class 6.
