This was a key takeaway for me from "Land the tech job you love" published by Pragmatic Programmers. Highly recommend this approach, with the caveat that you should either find out what the company is willing to pay in advance or really want to work for the company. Remember, money usually isn't the primary reason to leave a company. That said, I'd also suggest a little negotiation. I played this game and forgot it was an offer... ;-)
