When I'm looking to hire I post on craigslist. I get some spam, but also fairly good results for a free site. I don't usually search the resumes, but I know a few people that hire from there almost exclusively. Chances are you'll get spam no matter where you post but craigslist is fairly diverse and they're pretty good about getting rid of spammers quickly.
Good luck on the job hunt
I have soured to Monster lately. The hundreds of ads and spamies that I get because i have used their services in the past was upsetting. For me, nothing good came out of Monster (I got THIS job from them and am jumping ship next week).
