Fr8er,
You did not mention what you are currently flying.
If you are getting PIC turbine now stick with it. Even if it is 135. If you are currently in the right seat on the Dash 8, consider how long it will be until you can up grade and can get more turbine PIC.
One thousand hours of turbine PIC will open alot more doors that SIC.
At this point you have enough total time you should not have to pay for training.
