Does anyone use an induction cooktop priced over 1 million KRW?

There are even ones that cost 1.5 million KRW, and they are incredibly expensive. I'm thinking of buying one while I'm doing my interior renovations, but I'm not sure if I should go for it.
6.6kW sounds great, but I wonder if I'll actually have much use for that much power. Or should I just go for the latest model since I'm buying one anyway? I'm torn.
