The only topper I've ever wanted was the Aerosmith one. Unfortunately I missed the boat. I thought they were too expensive when they were new. And now the going rate is $1000 for it. So Stern got exactly what they wished for. Though, I'm not sure it helps them. They sell less toppers for more money. It's the exact same way they price NIB games. They sell less at a higher price. Good for them.
And no, there is no way in hell I'd ever spend $1000 for an Aerosmith topper. Some of the games I've bought in the last couple years were cheaper than that.
