Great thing about indeed is that it consolidates all the various job sites. So you don't have to search dice.com, monster.com, careerbuilder.com, etc individually.
Couple more tips.
1. Touch up your resume on LinkedIn and start checking some of the groups there.
2. If you start talking to headhunters, make sure that you don't end up having two or more submit your name for the same position. That's the kiss of death for your being placed there, because the company then wouldn't know which one to credit for putting you in contact with them.
3. Along the lines of 2 above, don't just send your resume out to a bunch of headhunters. They'll all farm it out to any and all job openings they know of, and then you'll end up with multiple submissions to the same company(ies). Instead, only let them submit your resume to specific openings that you have discussed with them, and discuss the opening enough with them to ensure that you haven't already been submitted there by someone else.
