Consider this. STLE was $8K NIB two years ago. It's the most I've ever paid for a Stern pin. It came out with a very pretty art package, and was very light on expensive, complicated mechs you interact with. This JJP machine has more flash, and a lot more tech built in. I'm fine with the $9K price - when you compare it with what you get on a Stern LE/Premium nowadays.
I have to play it more while I'm here at Expo, to decide if I want to get one. When flipping the shots feel compelling and there is a lot more that I haven't seen yet. It just oozes quality and innovation but I need more time on it to judge the fun factor.
