Actually, so far it really is looking good. I've had the chance to look at several of the models at the local GW store. They are aware of the existance of miscast models, and the policy is to replace any bad ones - which actually happened when I was at the store today - a miscast marine model was replaced, no hassle, no problems.
Point is, you don't need to accept bad products. And the models I've seen look great - crisp detailing, easy to work with, and now I've also had a tutorial about assembling them - washing IS necessary, by the way...
