Here is an official SpaceX video of the Falcon 9 Reusable that they are working on.

Here is the video: http://www.spacex.com/assets/video/spacex-rtls-green.mp4

This is more than a concept, SpaceX has already submitted a draft Environmental Assessment to the FAA for an experimental version of the reusable first stage. See that document here: http://www.faa.gov/about/office_org/...Grasshopper%20Draft%20EA.Final.pdf

Landing the first stage at the launch site didn't make a lot of sense. It would be going 7 or 8,000mph in the wrong direction hundreds of miles away. Maybe on a barge if it's that accurate. The second stage could land back at the launch site after going once or twice around the planet.
Customers would probably pay a hefty premium if they needed full payload capability and had to give up recovery hardware and fuel, but the price should still be lower than the competition.
Elon gets a little carried away with potential cost savings. I think he's finding out that equipment manufacturing costs are a lot smaller percentage of total launch costs than he originally anticipated. If the rockets were free, they'd still cost a lot to launch.

Angara - forever delayed Russian next-gen rocket - has reusable first stage as an option for future development. However plan is to use winged first stage sections with a turbofan engine to land on a regular runway.
I don't see rocket thrust of main engine as a good landing option - but maybe they know what they are doing. Or maybe they don't - reusable second stage sounds a bit too crazy for me, so maybe it's all just a big joke.
