Well, A NIB that was physically available in real time for pick up just went for 9k. I have no idea what value the future promise to own one is. Regardless of the reason, either someone will buy it or someone wont.
I have experienced first hand that certain prospective buyers of anything will low ball the crap out of you if they think you are desperate for a sale.
I think a fair price for a future promise to buy a Woz is anywhere from invoice too whatever they go for now for a future promise. As long as the buyer isn't loosing money (except for the time it was actually tied up) on their investment in JJP, there should not be a problem. Not all investments give a return.
