http://www.play-asia.com/paos-13-309e8034.htmYes, they do have them (erm, one). I was thinking about importing one of these before not too long, and when I do, I'll have a full review up on the site.
Yes, they are a pit pricey, but if you think about it, this is the only memory card you will ever need forever. Although 3rd party memory cards are always suspect, your computer's hard drive is not, so you can transfer saves onto your PC instantaneously, and if the card ever goes screwy, you can just swap the saves back on to it (or another card).
However, I must say that the Interact 16x card has perfomed perfectly for me. As a recommendation to everyone, when using any third-party card, follow this rule: First party games go on first-party cards, and third-party games and first-party back-up saves go on third-party cards. If you do this, you'll never be screwed. (Unless your brother erases your 16x card twice when he goes to play a Japanese game and leaves it in the GameCube, grumble.)
