If you're selling the same widget in 24 colors, you may have too much duplicate content to help you. In that case, do your single page with lots of diversity in your content so people can find you in a variety of different searches.
If you do feel you have to go with a single page, you might also consider some internal pages related to what you sell to help boost your rankings, such as a 'widget care guide,' 'widget comparison guide,' 'history of widgets,' etc. This will provide a little more spider food for the search engines.
