One of the first papers to use the Agilent Tech to do targeted re-sequencing.  I can't wait to get my hands on a PDF.

The impressive economy of this paper is that they targeted (using Agilent chips) less than 30Mb of the human genome, which is less than 1%. They also worked with very few samples; only about 30 cases of Miller Syndrome have been reported in the literature. While I've expressed some reservations about "exome sequencing", this paper does illustrate why it can be very cost effective and my objections (perhaps not made clear enough before) is more a worry about being too restricted to "exomes" and less about targeting.
