Well, here's a review of the Trumpeter 1/350 North Carolina by a critic whose views I tend to respect: http://www.modelwarships.com/reviews/ships/bb/bb-55/350-trump/north-carolina.html . I do remember reading, somewhere or other, another review that really shredded it, but I can't remember where.
The price puts this kit out of my ballpark, but I do have the Trumpeter 1/700 version. It's pretty high on my bucket list of kits in my stash that I actually want to build. (The North Carolina is a popular model subject in this neck of the woods - and relatively easy to research.) Personally I'm very impressed with the 1/700 kit. With the help of some photo-etched parts from White Ensign it has the potential to produce a superb model. (Which is not to say that the one I build will be in that category.) It even has countersunk deck planking seams.
In all honesty, as a former maritime museum curator, I wouldn't put a lot of stock in the typical museum employee's evaluation of a ship model kit. I suspect Tankerbuilder talked to somebody who works in the gift shop. I'm well acquainted with the ship's curator and education officer; they're both walking encyclopedias about the ship herself, but neither of them would claim for an instant to be really knowledgeable about plastic warship kits. For better or worse, it's rare to find a ship model enthusiast on the staff of a maritime museum.
At the risk of taking this thread off-track a little, North Carolina (and Washington) enthusiasts (I know there are quite a few) ought to know that the Trumpeter 1/700 kits representing those ships are quite different. The Washington kit actually is a quite accurate representation of both ships as they were built. It has the 1.1" anti-aircraft gun munts, the early radar fit, and the "gouge" in the port side of the forecastle. (The biggest modification to turn it into an early-war NC would be to add a couple of small platforms to the after Mk. 38 director tower.) The North Carolina kit represents her late in the war, with 40mm gun tubs (including the two on the fantail), the "gouge" plated over, the extra platform on the forward superstructure, and dazzle camouflage. (I haven't done a lot of digging about the Washington, but I suspect the NC kit - with that platform omitted - would be a good starting point for a late-war version of her as well.) Fortunately both kits contain plenty of 20mm Oerlikons and .50 cal. machine guns - though those parts aren't quite as well detailed as the best available in the scale. (And the armament sprue in both kits includes both 1.1" and 40 mm anti-aircraft guns.)
Youth, talent, hard work, and enthusiasm are no match for old age and treachery.
