The new issue of
Armour Modelling is carrying an ad for Dragon's teensy 1/144
Panzer Korp series, which come two in a box for 500 yen (about $4.50 USD).
The lineup:
Sturmtiger and Bergetiger
Maus and Tiger I (early)
E-100 and Tiger I (mid)
38(t) and Pzr IV D
They really look good, too.
By the way, these are kits, not pre-builts.
Now my big 1/35 E-100 can have it's own Mini-E!
