There's an LCVP kit by a French company- Fonderie Miniatures, IIRC. Squadron carries it, and it has been reviewed on the web. As I recall, it is a bit of a limited run kit, and requires some work. It also costs 3-4 times what you'd pay for the Lindberg kit.
BTW, The Lindberg kit is 1/32 scale, at least according to the box. My concern about that kit is that the transom doesn't match the drawings. All the drawings I see has the transom of the LCVP in a shallow V, while the Lindberg kit has a rounded shape.
