I picked up a replacement for mine a few weeks back, too.
Tracks were a bit cactus, lacking missile and it was not in box, but for $15 AUD I thought it was still a bargain - especially when there was a diecast toy trader further on selling one (with box, but also without missile AND the canopy was cracked on the cruiser) for $90. Tracks to suit were located and fitted (ww2 half track 1/35).
Ironically, the same week they republished the original cursed earth stories (uncut, complete with burger wars) and it sold out within hours.
