i'm guessing it is slightly limited (probably an inital run but no repeated production runs), but not like 'only a few thousand in the world' type of limited.
that said, if i start hearing that places are selling out and they are selling in ebay for more than what they retail for, and i happen to go past a shop with one in-store, i will buy it and stick it straight on ebay. one of the joys of living in a smaller town. may may get smaller quantities of stuff, but they also sell out slower.
