>>9053338Revive Char's Zaku II (middle). Purportedly the most advanced HG Zaku yet, with few seamlines and a choice between traditional hard plastic skirts or a seamless flexible one.
The Origin ones (right) are are also fun and pretty good kits. You have many options, colors, and gear loadouts to choose from there if you wanna go that route. The RG (left) I have not built, but I have heard it has issues since it was made so early on in that line.
