Red Roller is a shipping comparison site that allows you to enter your package details into the Red Roller engine and Red Roller then gives you a price and service comparison for USPS, UPS, FedEx and DHL.
The service is still in beta, but it looks very promising especially since it integrates with eBay and allows you to print postage from the carrier of your choice.
The service is also free.
I did a quick package entry from Seattle to Washington DC and found prices ranging from $1.73 to $69.73 and delivery times from 1 to 9 days.

From the Red Roller Web Site:
We're the world's first Internet-based shopping service for shipping packages, and as if that's not enough, RedRoller is FREE. We help our customers make better shipping decisions by giving them the power to quickly compare the rates and services of top carriers and then ship with all of them from one location. You might say RedRoller is a revolution in the evolution of shipping!
