there are more types available in 1/144, and they are actualy often cheaper than the smaller 1/200 scale models. however if you have limited space the larger 1/144 scale might not be an option. The best quality is revell germany. their A 340/330, A 320/321, 737-800, bae 146, and fokker 100 are all great kits. Minicraft is also pretty good for the most part. their dc-3, 737, Md-80 series are all very good. The dc-6, electra, and constellation are a bit lacking. the boeing 377 and 707 are pretty good, and their 757 with Pratts is nice too, though the rollce-royce version isn't so good. Airfix? EVIL. their kits are of a much lower quality.
When in doubt, one B pump off
