What capacity SD card should I need for a Twilight Modded/Homebrew Wii?

I haven’t turned on my Wii at all this year; the system’s content is all but dead. I’ve decided to run with the Homebrew Channel to at least justify keeping the system at this point.

What capacity SD card should I pick up to actually hold the content? I know most of the ROM information will be tiny, but I also hear there’s a ton of it out there.

Err… this thread will probably be locked in due time. But I can tell you that for purely homebrew only purposes 2 gigs is cheap and plenty.

Just for the record I’m not necessarily talking about illegal ROMs.

The answer, btw, is “The Wii only supports up to 2gb at a time.”
