SD card speed for Wii?

[tfbit]

I'm trying to figure out what speed SD card to buy for the Wii. Does anybody have any solid knowledge as what speed card will deliver the best bang for the buck? If I get a new Sansdisk Extreme III card would it make much of a difference over a cheap SD card?

Dont bother with anything extreme. VC games will load into memory, and saves will load quickly regardless.
