Joel, it's a fair question and to each his own.
On at least two other fora, arguments over the kit came to virtual blows with one member banned from both sites. I'm not a Spitty expert, but those who are have described the kit's errors, including oil cooler, wheel well bulges, nose shape, propeller blades, and the cockpit.
Now, some modelers don't give a rat's ass about those problems, and 95% of those looking at the kit will say "that's bloody well a Spitfire." But for those who are looking for more accuracy, these AM goodies will be welcomed.
Different strokes for different folks?
