Here are some images of Bandai's 1/48 scale Jamstec Shinkai 6500 Manned Research Submersible.
This is one of the best kits I have seen in a long time. The detail is amazing plus there are lots of moving parts and removable panels. It even comes with a lighting pack.
What I found interesting is the lack of glue that was required in assembling such a complex kit.
It also comes with one of the most complex display stands I've seen.
However this kit isn't cheap. It retails at around $100 CDN.
