I've had good experiences with PNYs and Kingstons, but not specifically for this purpose. My Wii just has a cheap "Team Group" card I got online. That said, considering the amount you're going to spend on a name-brand 32GB SD card, why not spend a little more and just pick up a hard drive? Wii64, DIOS MIOS and USB loaders can all read from one, and you'll have at least ten times the storage space.
