I've always enjoyed looking at Seiya SH Figuarts. They are really nice! There's a local snack shop here where the owner has a bunch of glass cases full of his figures. On one side are his Seiya figures, and the gold ones are soooo nice looking! It looks like nowadays they are mostly Bandai exclusive, and every time I see one import site I use put them up, they sell out pretty much immediately :x
They're actually not Figuarts, they're Myth Cloth/Myth Cloth EX (and I think they made a new line), but close enough I guess. :)
Like other high end Bandai items like Macross valks, they sell out almost immediately when they're posted on amiami and the like. I have no idea what it's like in Japan, though, I assume they come out in specialty stores and are still hard to get? It seems like the series is still fairly popular in Japan and LATAM considering they continuously make new anime/manga spinoffs.
Someone mentioned that in the US, the toys were plentiful, but those were the Bandai America toys. They actually made a bigger set of "armored" toys but I don't think they even finished the main five, let alone branching out past that. Otherwise, all they had were like crappy action figures. Though it was like a golden age of domestic Bandai toys, they had SD Gundam toys, Ultimate Muscle toys, and MSIA Gundam toys made almost exclusively for the US.
