Never pay for homebrew.
Homebrewinstaller ($29.95) and Wii Homebrew Installer ($15) charge money for files and information available for free on other sites. Both of these web sites are scams. For information on free Wii homebrew, I recommend visiting WiiBrew or HackMii.
For those who are unfamiliar with Wii homebrew: It is not equivalent to piracy. The purpose of many homebrew applications is to extend the functionality of hardware past the limits of official software. For example: The homebrew application NuGaSa allows Wii owners to backup and restore Gamecube save files from an SD card.
The owners of WiiBrew, HackMii, and Brainstorm Warning do not condone piracy.
