When it comes to hg kits I will basically buy anything since they are so cheap.
I dunno, some HG kits are pretty iffy. I remember the HG Flags from the 00 line being really flimsy and pretty much useless without a stand. Usually HGUC kits tend to be WAY better because they know that UC fans are more particular, while the AU stuff tend to be cheaper for more casual fans in my experience. IBO seems to be an exception?
