I'm at a similar level of experience as you at roughly the same place in my career. I've only interacted with one recruiter and it worked out very well for me, leading to my first full-time "real" position at a company with some other fairly talented developers from whom I gleaned a ton of knowledge. I guess it's a YMMV kind of thing. They didn't ask me to sign or pay anything, they just asked for technical qualifications(languages, tools) just lined up multiple interviews in one day for me that were a rough match.
