I would not by a 180 now since the 210 came out.
With the weight about the same I would take the 210. I got to fly a 210 at Kentucky and noticed it was burning less fuel per flight then the 180.
A big thing about the 210 also is it runs allot cooler. That means less wear and tear on the pipe and the turbine.
One thing to keep in mind is its about 47 pounds of thrust! So people need to use their throttle stick accordingly. Already had a friend blow his plane up in flight with the 210 flying it to hard. You need to pull that left stick back with the 210
