If you're moving away from the US you'll see a significant drop in salary though. The market salary down here (even for top developers) is significantly lower at around $60k/year; but so are the costs of living. I live comfortably off $8500/year.
I started working here in a startup and I moved from Helsinki. It was a bit hard to get the job because I didn't know anyone and any companies. It took around six months to find a great job and I had to do everything to prove my enthusiasm and skills for the employers.
I love what I do and I'm a smart programmer but when nobody knows you, be prepared to make some extra work to convince your employers.
Depends on whether you're moving from popular dev centers such as Silicon Valley or New York City, and of course it also depends on where you're moving to. My guess is wages here in Denmark should be able to match or beat US wages outside of Silicon Valley and New York City.
