I've yet to lay hands on any of the Takom kits regardless of subject. I've heard nothing but good things about them though. I'm more of a modern US armor builder, so I've been getting the newer AFV Club M60A1 and A3 as well as newer Abrams kits.
I know other brands of King Tiger kits have hit the for sale forums because they have to have the best and are selling off in order to obtain the Takom ones. So pretty good deals can be had if you want a good, but not the best, King Tiger.
