I think what Patio11 would typically say to this is that you shouldn't base your expectations / negotiations on "market rates." The problem with a set salary (or getting paid per hour) is that your pay is tied to a set unit no matter what value you are creating for the employer.
We only have one shot in this life. We have chosen development as our professional practice. We should be looking to take that practice to the highest level that we can reach. Basing our salary on market rates is basing our value on industry average (or the level of mediocrity if you are more the glass half empty type of person.)
Ultimately, your place is to make money for the company. This is what you should be basing your value on. There is $X on the line and you have great influence on moving that number. If you aren't in this position, then keep looking so that you can get max value out of the lifetime of your profession.
