i would say tamiya also,only the king tiger idlers need some upgrades the rest is as good as the other tamiyakits. Live and learn i would advice ,

the sherman , pershing and the panther are first class kits no upgrades needed, tamiya don't need upgrades for its soundsystem , its digital recorded with a descent speaker, you won't be disapointed

also my leo 2A6 is also a very good runner but it isn't cheap, its the expensiviest of all ... or you must be lucky like me i bought him for 580 dollars from a guy
