We use Limelight which is much cheaper than Cloudfront or Rackspace at 95th % > 1gbit. They are also well dispersed in the world minus South America. Akamai is still by far the best at prices roughly equal to CloudFront and Rackspace (at 95th % > 1gbit). CDNetworks is still the best in Korea. ChinaCache is the best in China (gov't owned probably..) EdgeCast most likely the best in South America. Australia is tough. Akamai still the best.
