I voted Kingston Japan, but its a Toshiba, but from another thread I gather these are basically the same. Also I have a Sandisk Ultra II. As far as I can tell both work fine. I don't really get many random crashes, and none so far that suggest the card is at fault (i.e. once with Harvest Moon but afaik it was a known HM bug). Also everything seems to play at full speed (again as far as I can tell) but I haven't done that THDJ test yet. I've said it before and I'll say it again. No complaints here. Yay!
