I only ever got the first generation of "Star Wars" models, when AMT brought them out in the wake of the first movie's release. I built them and enjoyed them, but I always wished they had also kitted the Y-wing and a regular TIE fighter, instead of Darth Vader's machine.
I built their original Millennium Falcon, and enjoyed it. People today turn their nose up at it, but in 1978 or so, it was just cool to have a model of it at all. And I built the 12" (or so) Darth Vader figure kit, with the glow-in-the-dark piece for his light saber. I could see re-doing it today, to see if I've learned anything since then.
The only kit I've built is also an older one, the scout walker. That was more recently, about 10 years ago or a little earlier. I think I got the kit in one of our club raffles. It's on the Shelf of Doom now, though I think I finished assembly, and got stalled at detailing it and making a Hoth base for it.
I would like to get the Razor Crest, too, but otherwise, that's about all I'm interested in building from the franchise.
