It's about $80 in US dollars. For some Starcraft II fanatics, it would be worth it. I am happy with my Logitech G5, which I got for about $46 a year and a half ago.
I just looked it up a little deeper and I now see that it is for sale much cheaper elsewhere, though there are still quite a few selling it for thousands. My initial google results were all on the high side.
I have a Razer DiamondBack 3G. Nice mice. Sticking with that n all.
