I use http://themeforest.net/ when I need a template for a throw together site. Most of the ones I have purchased have been well organized and their prices are better than some of the other sites. The down side is that they do not seem to have as extensive of a collection as some of the other sites. That being said, I have never seen a template on their site that looks like it was meant for geo-cities or myspace either, so that could account for the fewer templates.
