Found mine today. It was in the overstock, so look up. $39.99.
...last weekend I saw shelf tags for it at the very bottom of the shelves, so I guess look down too.
It's a nice piece-- fully-assembled, no labels. Lots of paint aps, great canopy, wonderful deco throughout but it's a little bland under the wings. I love the paint job on the engines, there's some blue on the cylinders which rotate the wings. I haven't popped in the rocket-firing guns yet to try those out. Also, the canopy actually latches shut which my 1984 B-Wing does not. (I have but have not opened yet my 2001 and 2008 B-Wings for some reason.)
It's really good. I think I paid $30 for my MISB one (which I opened, of course) back in 1989, so seeing this for $40 is something of a bizarre head trip. Nice box, nice design, nice deco, good deal. Can't wait for the Y-Wing now!
