Snowboards for Women
http://www.snowboardsforwomen.com
Snowboards for Women was founded as a result of me shopping for a snowboard for my girlfriend but being unable to easily find boards for women. It has real reviews from lady boarders as well as price comparisons among all the major snowboard retailers to make sure you get the best deal.
I update the site monthly from a data feed that I then parse and insert into the master database. This way, the prices and product images are always up to date and everything loads quickly.
Other people seem to find it useful as well - the site ranks high on Google search and it's my biggest traffic generating site so far, so I'm quite happy to have made something people want!
