I built 7778 Midi-scale Falcon. I liked it. It makes effecient work of its pieces, and forms a substantial and solid model. The shape is just right, too. My only real gripe is the stickered canopy. I got lucky, bought a used one, and the sticker was straight. But it's still just a large cone with black stickers...
Either way I know midi-scale gets a bad rap, but the Falcon is a decent set, and the perfect size for a compromise in display space. Fun build, too. I think I might open my midi Star Destroyer and build it now.
