Personally, if it doesn't have the wheel, I wouldn't be interested.
I don't need another, but if I did, I would probably go about $100, same as I would for a newer one with everything needed to vape out of the box. (assuming 10-30ml juice, 2 sets of batteries, and at least 2 atomizers or similar)
used is used, and there is no shortage of new Buzzes available for purchase.
