Do you know which finance website I'm talking about?

I can't quite remember, but I think I typed in my salary and current city, then my salary and another city on a ';conversion'; type chart which showed me the difference of how far my salary would go in the new city compared to the one I am in. Also, there was a chart that showed me the differences in cost of living of the 2 cities. Can you help? (FYI: it isnt the salary wizard at cnn.com)
