I'd like to recommend Dohop (http://www.dohop.com http://www.dohop.com). We try our best to not only get the cheapest prices but to also display the complete price, that is, including potential credit-card fees, booking fees etc. We also have a nice affiliate-service where you can set up your own Dohop-powered flight-search engine on your site and customize it to your liking.
