Not looking for a p!ssing contest but:
Have you thought about doing the JAR "conversion"?
I was pretty much in your position ie. European with FAA licenses and sitting on a couple thousand hours. It took me 4months from first day of studying JAR ATPL until holding a freshly signed JAR CPL with ME-IR privileges.
My guess would be that flying 200hrs Beech 1900 on your FAA ticket, will not make you more employable in Europe. I have spoken with quite a few pilots on the N-registered turbine equipment in Europe (used to be one) and the experience level is generally VERY high.
Now with both FAA and JAA licenses it's a different ballgame. I landed a job with a reputable corporate outfit, paid rating and decent T&C.
