Well I got lucky and got one from abebooks for $50 including shipping. Unfortunately the yellow band tears easily (it looked like most for sale with the band had tears), and mine tore in transit. Recently the ones I have seen for sale have been w/o the band. To me, the band, torn or not, increases the value.
John, not sure how many were made but I think I saw that 200 were made available for the Australian market. I've been looking for a Shift arc but no luck so far. I think Shift will have much less printed due to the popularity of Wool so far.
