dragon models have come out with so many kingtiger models in the last two years, including the new battle of the bulge they just released this week, do they all have different enough items to buy them all. i know that the turrets are different on some, but do they all have some extra item that warrants getting them. like to know what you folks think.

Hi Bob,
While I haven't bought any of them, I know that they represent different versions of the King TIger, henschel, porsche, zimmerit, no-zimmerit, 18-tooth sprocket and so and so on, it really depends on which vehicle you would like to build or catches your eye.
I haven't really heard anything to bad about them, I just prefer the Tamiya King Tiger except for the price.
With all of the extras that DML offers, if you are not worried about accuracy, then go with one of the DML KT.
Regards,
Robert

I think, it depend on which way you choose to build the kit. If you like build ootb, dragon is better choice. but if you want to add some PE, maybe Tamiya is the right choice
