I just looked and saw various prices for the same sculpt (all with the same photos of the hand holding it at various angles).
I also went for the cheapest option. It was $37.78 shipped, and marked as the last one.
The next cheapest listing for the same sculpt is $53, and before your confirmation that you got the cheaper one I was wondering whether there would be a difference in quality between the options.
The one you got looks a massive improvement over the soft, translucent Black Box original.
EDIT:
From the price breakdown it was $28.49 + $2.99 postage ($31.48). The extra $6.30 was the VAT that Ebay charges up front.
