Any 1/350 battleship, done properly, is a major project.
However, both of BWN's SoDak class BBs, or the WeeVee, are great kits.
I would suggest getting your hands on a Tamiya Missouri or New Jersey, or any one of their BB kits (PoW, KGV, Yamato, Musashi, Bismarck or Tipritz) to get your feet wet first. The beauty of most resin kits is that you can get back what you paid for them in most instances.
