I work at ITA, but not on Needle. I have played around with an internal demo, but not for anything serious; I found it easy to use and to require little or no programming.

Check out the video: http://www.needlebase.com/videos/video1

Part of Needle is a browser interface that helps you click through a website and tell it what to scrape without writing any code. It's pretty smart about reducing the amount of work you have to do; that starts at 1:50 of the video.

Needle is currently in open beta; try it out for yourself!
