I ordered a Panther and a StuG IV model from eBay recently.
There are 1:71 scale 4D puzzle models that just clip together.
Unfortunately I received two StuG's instead of the Panther, so the Panther is still coming.
I like that they have some paint on them already, but it doesn't really match any of the camouflage patterns you see and they need some decals.
So not quite table-ready, but better than bare plastic, and very quick to assemble!
