Slightly cheaper than from TGG, currently $129 + delivery. Seems to be plenty of stock around Brisbane.

Just vouching for the mouse. I got it during Black Friday, and it's a great mouse. I don't use a lot of the additional buttons but the contour is great. I still use it to game even though people say it's a bit heavy for that (I don't play FPS)
