New: Google Custom Search Business Edition

A bit of a mouthful, Custom Search Business Edition is Google's new paid service that allows sites to utilise Google's search power for site searching, but without ads.

At $100/yr. it is substantially cheaper than forking out $2000 for a Search Appliance, although it seems that any pages crawled would appear in Google's regular search results as well - so it's not a cheap way of searching an intranet of private data.
