I've used Dice for some time. It was pretty productive for CONTRACT work.
I went independent about 8 years ago. For the first few years Dice provided several decent opportunities. However I now have a reasonably well established reputation and client base so it is not as important. I have also been out in the market long enough that most of the recruiters with anything decent have my info...
My experience is probably not typical. I've worked with SAP since 1994, have a highly polished resume, and lots of industry references / contacts. High demand skills, reasonably well connected, and strong resume.
