There's a Zone Classic in my pro shop. 15lbs I'm pretty sure, the price is $200, but that includes drilling and such. I dunno how much he would want for it NIB.
I'm pretty sure it's the green pin. The ring around it is definitely green, but the pin was kind of dark and I was in a hurry, so I didn't get a good look. Let me know if this is the right one and if you may be interested.
