That is a great site, full of information and pictures. The revell kit, even oob, builds into a really nice ship model...with over ten built so far, I still have more in the stash ! Save yourself some puttying grief by using white putty instead of acryl blue, green, or red though. Most of the parts fit together quite well, and only require a little bit of work.
Squadron makes an excellent "Schnellboot in Action" book, one of their best, actually.
