I' ve been checking out this board but haven' t seen anything on an issue I' m currently going through.  I was hoping some of you out there could give me your opinions/thoughts on this.  particularly the ones that have had to make the same type of decision.

After spending 8 years in Financial Services and completing my MBA in Finance & Marketing in the Northeast, I decided to take a chance and go to Dubai, UAE to see what sort of roles are available for someone with my experience and education. The first 4 of my 8 years experience were as an Investment Consultant/Business Development officer in a Int' l company and while I' m fairly confident in this type of role, part of me is interested in learning some new skills, and expanding my abilities to make myself more marketable, and more importantly, to not get pigeon holed in Bus Dev. 

Since coming to Dubai, I' ve been able to find a position in Investment Banking where I would be at the bottom rung of the ladder and would learn a considerable amount, from new skills to general knowledge of that part of the industry.

At the same time, I' ve found another Investment Consultant/Bus Devel position with a local bank.  While I would be working in a new geographic area and would learn a new geographic market, Its pretty much the same position I once held with little opportunity to learn new skills.  But this position pays roughly 75-100% more money than the other.  (General expenses, in particular housing, are rather expensive over here.)

So, long story short....What' s the right move here?  Is there something I' m not factoring into the equation?  Do I run the risk of getting pigeon holed, or do I seriously tighten the belt strap for 2-3 years before Im at par with the original BD offer?  New Skills Low Money vs. Old Skills Big Money?

Would really appreciate any thoughts/opinions.  As I need to make a decision in short time, the earlier the response the better.
