LOL. Actually, they had two Rocks that I was considering instead of the GP9. An Athearn powered and dummy SD40-2. But the two were right next to the P2K, and there was no comparison in looks. And I have enough Rock engines for the time being (although they still need to be converted to Kadees), so I went with the better looking engine. A decision which I don't regret (although the more Rock units I have the better).
