Ask HN: Good agency/website to find short-term contract programming work (nyc)?

Anyone worked with a good recruiter or agency in NYC to find a contract job?

I'd like to get a short-term contract programming job in a big company with deep pockets and high headcount so I'm as anonymous as a grain of sand on a beach - just to pay the bills for a while.

I'm thinking about approaching some of the big national recruiting agenencies - KForce, etc - but I'm concerned they have so many heads they may not be very "attentive" in terms of finding work for me.

Also, lately there seems to be a lot of Indian agencies trying to disguise themselves as local agencies but when it comes time to get paid they have a reputation for being less than diligent (I don't know how true this is - just anecdotal reports).

Would appreciate any feedback or recommendations people may have on particular east coast or national general-purpose employment agencies that focus on I.T.

The rentacoder-type websites are useless because of the low rates. But perhaps there are sites that specialize in contract work that someone could recommend?
