The ES Gokins are easily the best figures Pizza Cats have ever gotten. They're expensive, but they're very well-made. There were two types of Bandai model kits back in the day. The one you posted (known as the "Mega Up" kits) has very little articulation and needs paint. The other type (known as the "Edomae Set" kits. pictured here) require no paint and are basically simple snap-together action figures. Both of these model lines are from 1990, so be prepared to scour Yahoo Japan auctions or whatever for however long it takes for one to show up.
There was also an unlicensed figure from China few years ago, but it's not as good a likeness as the ES Gokins.
