What are the differences between the Tamiya KT and the Tamiya Panther kits? Is it just new vs old molds that make the Panther prices so much higher, or are there noticible improvements? I'm really biting at the bit to snatch a Tamiya and I am debating between these two models. The $125 price difference at AAF is certainly a factor as is the availability of a HL Panther. Is the KT the full Tamiya wet your pants experience or due I need to jump to the $700 kits?
