CSS style switcher
This plugin allows users to select their prefered CSS style sheet through a drop-down edit, and stores this info in a cookie. In plugin options, you have to specify which CSS files you have (without .CSS extension, just filename, to conserve space), set descriptive names of these styles, and specify which one is default (if no cookie is stored). Plugin will also check for deleted styles (and supply a default one if it doesn't exist anymore).
