Does anyone have pricing information on Google's Custom Websearch?

Google Custom Websearch

I am thinking about skipping the $599/month Silver/Gold search in exchange for the Custom Websearch so that I can have guaranteed indexing for my 5,000 page web site.

Here's Google's "promise" for Custom Websearch customers:

--------------------------
All WebSearch licensees receive index updates on a regular basis to ensure fresh content.
[google.com...]
--------------------------

You have to contact them before signing up, so I was wondering if anyone out there knows anyone else that is paying for Google's Websearch service. Everyone knows that Atomz starts at $15,000/year, what do you think Gooogle charges?
