Unfortunately, the Tiger's design was a bit too complex. For instance, due to its weight, it was not able to go over small bridges, so it was designed to ford water up to 4 meters in depth. This meant that it had to be equiped with additional systems for breathing, ventilation, and engine cooling, the hull had to be sealable, and some of the compartments had to be floodable so it would not just float and get dragged downstream. Likewise, it introduced a new design for several rows of overlapping, interleaved wheels which gave it a wider track, better able to distribute its huge weight. All this increased its manufacturing complexity and cost, which resulted in less tan 1500 being manufactured during the war. By mid-1944, it was phased out of production in favor of the Panther and the Tiger II.
Stackpole Books has a two volume narrative of Michael Wittmann's exploits as a Tiger I commander, which provides great insight into the Tiger's development, the operations of a tank battalion, and the Tiger's performance in combat. In terms of Toy Soldier manufacturers, we have a couple good examples courtesy of the usual suspects, 21C and FOV.
