Gech, that website isn't very accurate. It looks as if all it does is compile averages based on its current users' registered info. I mean, there's no way in hell that a Staff Accountant makes less than a High School Teacher in my area. I've talked to all of the local firms and from what they tell me even the introductory pay is at least $5,000 more a year than Payscale's "average pay".
As for where I go to check incomes, I tend to use either
monster.com's salary search or I go check out
Salary.com for a second opinion. I think Monster.com even has a price-of-living comparison so you can see if that boosted pay in the big city is really worth it or not.
Jam it back in, in the dark.
