It's the only 350th kit out there (the Minicraft kit's a repop) so it's kind of a moot point if you want a model of the ship in that scale.
That said, it's very buildable; the only problem I had with mine was that the top deck had some gaps near the superstructure, which was designed with some parts to poke up through the deck.
