I would go for the "LongProsper" models. Although a bit limited in choice they give a great look with there 1/200 models. Especialy the United 747-400 I also have a EK 777-200 1/200 model but i'm not sure who it's made by. I prefer the plastic snap-fit as they are MUCH cheaper then the metal ones and give a better "new look" effect (more shinere)
Your choice though!
