For me, this is the most exciting group by in months. That is entirely due to the number of choices and the added rows to the profile. Because of that, I expected to pay more.
Unfortunately, I don't think many people understand how more kits and new tooling contributes to the price of a drop. This is evident by the number of "why do I have to buy more keys than I need" comments.
Anyway, I think you did a great job on this one and I'm all the way in.
