Well, first off it depends on if you want to delve into the whole franchise, or just stick with Gaogaigar at first.

As far as Gaogaigar goes, the original '97 toyline is incredibly durable and decently engineered for its time. Newer toys tend to just be really expensive and somewhat fragile versions of Gaogaigar himself.

If you're alright with touching on other Brave series, Might Gaine and Goldran both have a lot of badass stuff. I'm really hoping to do a video on God Silverion sometime soon, he's a really well-done combiner for his time.

Dunno about availability though...the most readily buyable stuff used to be Sonokong's official Korean releases but I dunno if they're still common.
