I think I got my current job from Indeed. Pnet is good, careerjet and careerjunction, Trovit is also worth a look. Most of these sites aggregate ads from other sites though - like Indeed and Trovit. Pnet and Careerjunction have their own original ads.
If you're looking for work this isn't a bad thing at all. I got some very profitable leads from agents when I was in the market. Just remember to inactivate your profile when you found work.
Pnet is actually not a very well put together site but it's the most active and maintained.
