Oh, man, Barry. That's a tough one. My initial reaction was the same as Terri's and Andreas', but I have the old Hi Tech Breguets and they're pretty good, though the CSM kits would be more detailed and better fitting. And the Albatros C.I is...never mind. I want them all. But, if they only did one, I'd like it to be the Farman. Or maybe the Voisin. Or perhaps the J.1. Or...
Cheers,
Bud
