I think you need to take into consideration the type of industry that the company is going to take you in. A lot (actually most) of the companies would low-ball their prospective employees, as it looks good in their bottom line that they are getting these developers for less paltry sums.

If the company hiring you is already an established firm with a good history in terms of professional's salary, then I would expect that you could go for a range of 100K - 150K. For startups, it could go as less as 50K and for medium sized companies, it should be fair to consider an offer from 60K to 90K.
