As much as I would like to get this, I've got the original Weijiang OSKO Nemesis Prime. Being in Japan, the official version might be cheaper, but outside, I'm not so sure.
I reckon the official version is going to be over 100 dollars outside Japan, whereas the original Weijiang version is around 130 dollars or so (possibly including postage) here: -

Also, there's the newly released Black Mamba version (although the lorry mode is different) : -

I suppose it's great that there are at least three great options for a large, film-style Nemmy-P.
