I've been wondering whether or not to mod my wii. I have for backups of my games and imports in the past on other systems, and have been searching for the best information on mod chips. If like me you want information about mod chipping your wii, i've found a website which gives a very comprehensive comparison of all the mod chips available. Please note, this site is for information, and is not selling the chips, nor condoning getting them! http://nintendo-wii-modchips.com/modchips_explained Enjoy.
