Go to salary.com. don't pay for the shi-shi foo-foo personalized report. You can put in the zip code or city, and type of position. While this may not be exactly in line with your job description, it gives you the range of salaries for different gigs.
Also, NEVER take the first offer immediately. The last job I was at, 3 of us started the same day. The other 2 took the first offer. I asked for more money, and extra benis, and I got it.
Even if you are taking a job where there is no room for negotiations, ie all first year attorneys at some firms get the same pay, NEVER say yes on the spot. Ask for 24 or 48 hrs to contemplate the offer. It helps them realize that you're mature and thoughtfull, even if you're as giddy as a school girl on the inside.
Good Luck!
