Hi MX5Miata, The White Huna has a very specific story, and cannot be compared to first Toa prototypes (and their kanohi). Question : what colour is the White Huna? White... Congratulations! Have you ever seen a white huna on any Bionicle set? No. This explains the price, that was also revised to be traded for 852293 Castle Giant Chess Set which is worth $800. I would estimate the first Toa kanohi prototypes to $400 - $500, but you know, the real price is the price somebody would be ready to pay to acquire it... About the first Toa prototypes, I would have a different point of view, as there are some significant differences in some parts, and these are really interesting for long lasting Bionicle fans! I would estimate them to $800 - $1200, higher price for Toa Pohatu if coming with the rock prototype. But as said, it's a high price for plastic parts, as some people will only see it. Good luck to you, fifi2004
