Im not entirely sure about the cost of it but I know it goes for twice the value of it.
What you get are the lions the sword and the pilots. I think there are accessories for the pilots.
If you are interested in more I suggest youtube it.

I would go for the newer diecast one. Ya thats a good choice! Comes with a stand.
Have you tried all the normal places to look such as amiami, hlj, hobby search, ny?
If you are having trouble finding one lmk and ill help look.
Or even ebay?
