The Lunar Models Seaview can only be recommended for experience model builders.  It is also one of the less accurate Seaview models, certainly unable to hold a candle to the somewhat flawed, but far superior Monsters in motion version.   If you're dead-serious about owning various versions of Seaview, then you'll want to have one.  Unless you excel at modeling, don't even think about building the TV version.  It's a conversion kit as seen below.
