What are the best Mac/PC Temp agencies out there?

I have in the past had luck being placed by www.aquent.com. Can anybody share some of the agencies the have worked with? I am looking for temp agencies in Los Angeles ares. I was recently let go of my job for attempting to enforce the IT policy. Just looking for ideas as to where folks look for agencies. I am currently trolling sites like craigslist, monster, career builder, and dice. Thank You.
