I had a chance to hit Klein's on Saturday and I saw this kit hanging on their pegboard among some other items. It looks like a really nice kit, though I couldn't see the castings very well through the packaging (rats!).
But it was not at all obvious from the labeling that this was a Z scale structure kit (the words 'Kit Z-02' are a bit too subtle, I think). While I doubt you expect too many sales from walk-ins to an LHS, it would seem helpful to have the words 'Z Scale Structure Kit' or some such printed prominently on the packaging somewhere. Just my 2 cents.
