Tiger, Jagdtiger, StuG, SdKfz 251, and Panzer IV, I like them all. As for tanks (German), my favorite, naturally enough, is the Tiger, for tank destroyers, the Jagdtiger, no question about it. (In fact, the 1:16 Trumpeter Jagdtiger is on my short list of kits to acquire.)
The Schiffer books in the Legends series are a great value, in my opinion; great photos, glossy paper stock, hardbound, good prices and with easy to read descriptions. I highly recommend them.
This is by no means all of the Tiger references I have, but does reflect the general spirit of the books I've been prone to buy in the last few years.
