Have you ever seen any of the BLACK VARIANT of G1 Powermaster Prime sold in Oz, and what is best prices you have seen him for?

Ebay prices are way up there, so just looking to get some idea of what is sensible to pay for it.

Could have asked in that "other" thread, but stuff gets steamrolled over every day and ignored there when 10 questions immediately followed, it, and everytime so far I've posted in that thread nobody answered anything.

Thanks for any tips pricemongers!
