You're paying for the recruiter's database of programmers. I get calls from recruiters who first contacted me 5 years ago, from time to time. That database is invaluable in most cities, where programmers are more sparse than in the west coast. If you have to rely only on people who are applying or putting their resume on Monster, CareerBuilder, etc. it can take a long time to find someone competent (I've seen it first hand). But recruiters have no problem calling up people they've placed as recently as a year ago.
