How much does it cost to get into the space needle?

The space needle cost 111.7 billion dollars to build (or maybe $21 million original construction? (See Wikipedia).

You will probably need to pay to ride the elevator to the top. This web site looks like the place for the cost of a ticket, but I don't see it. [http://www.spaceneedle.com/] It seems like I payed around $15 a long time ago.
