Actual cost of current Rocket systems

Hey, I am doing a reserch paper, and I am trying to find the average costs of launching on American launchers - specifically, the Delta IV, the Atlas V, the Delta 7000 series. Also, if they are still in production, the Taurus and the Pegasus. I initially used the figures from encyclopedia astronautica, but then I came across some other figures - so does anyone know where I can either have or know where I can get accurate launch costs? I'd like to include, unless there isn't any sort of standard, launch range, third party insurence, and integration costs for each rocket.

According to Elon Musk of Space Exploration Technologies, no launch provider makes their prices public. SpaceX does, but have not yet actually launched a rocket.

At home I have a link (only have to find it *g*) with launch cost ranges. In the meantime you can take a look at http://www.futron.com/pdf/FutronLaunchCostWP.pdf

edit: just found the document where the link to the launch cost table were from:
