>>5354953The HG Zaku II is a really really nice little kit and pretty fairly priced at $12-15 on Amazon.
However, the problem is that HGs are even cheaper on actual import sites.
You should read the Gunpla General's OP copypasta. It has a comprehensive list of some of the import sites used for Bandai kits, which also happens to apply to many of the other Japanese toy lines posted on /toy/ as well as resources for different needs.
One that's super-useful, for instance, is Dalong, a repository of most modern Bandai kits and models. Though in Korean, it's easy to navigate and understand and provides very good rundowns of the various modern kits of a medley of ranges.
