What is more important? Finding a position where you are or moving to where the position is available?

I think it all really depends on not only the person but the company. A few things I ask myself before considering moving to a new position beside what is the pay increase are:
* What is the current business position of that company?
* Is there room within that company to expand in a few years or will I be left looking again in a few months?
* How can working for that company help me professionally grow when compared to those opportunities at my current position?

Yes, of course more money is always nice but sometimes a few extra dollars are given in trade for other limitations so it is never a cookie cutter style answer.

This really depends on so many things but mostly on you and how you feel about the situation.

Could be the circumstance or the situation. "supply and demand"
