An SLS launch is projected to cost $500 million.
A single Saturn V launch cost up to $375 million in 1969 — or, in today’s money, a few billion dollars.

I think SpaceX's grasshopper setup is more promising. It doesn't need to withstand the same pressures that the shuttle had to because of the altitude at which it returns to Earth, so there's not so much to refurbish. That, and it also comes down like a pencil rather than like a rock.
I agree that SpaceX's setup is more promising. The fact that they're slightly modifying an existing expendable rocket that's already cost-competitive means that any reuse is just a bonus. They can throw away a bunch of boosters as they work on the problem, which wasn't an option with the shuttle at $2 billion apiece just to construct them.
Edit: I'm rooting for Sabre & Skylon, myself. Perhaps not for big payloads but for 'naut travel, anyway.
That depends on whether or not 2017 is foreseeable (http://en.wikipedia.org/wiki/Commercial_Crew_Development). Since 2012 the US has had a craft that is capable of taking people to and from the ISS, NASA just wants to do an excessive amount of testing and incremental improvements before we trust it (http://www.newscientist.com/blogs/shortsharpscience/2012/05/...).
