I'm not saying Athearn did a bad job with their Genesis diesels at all, but I have limited funds, and I'm rather happy with what I have, plus their RTR unit. I'm pretty sure the Frisco models will be flying off the shells justthisfast. Athearn has definitely stepped up their game with the Genesis line. I'm still waiting to see what the Genesis GP7 looks like in Frisco colors.... Somewhere in my collection I have an Atlas/Roco GP40 I painted & detailed for Frisco- it got retired when I built the Athearn GP40-2s. As I get engines with scale-width shells, the wide-shell units become display pieces.
