The last few jobs I've gotten I've gone in with a number I wanted, told them what it was, and gotten it. Prior to even attending the job interview I'd come up with a reasonable number that I was happy with. Then when the conversation comes up I know exactly what I want, and I haven't had to deal with tedious negotiations with recruiters. The closing process is easier on everybody, and either everybody gets what they want, or we find out if it's not going to work out right away.
