Boxing Day sale. Available in Black, White, Matte Grey and possibly Green/Brown.
EDIT: Looks like the only version still available for purchase online is White.
EDIT 2: One left, in white. Looks like there are still other colours available in store.
The M40x is still in stock for $111 in store or $127 delivered.

EDIT 3: Looks like the site has crashed.
EDIT 4: M50x seems to be sold out although posters seem to be finding stock intermittently. M40x still available but in low stock.
Just ordered the Dark Green version for $151. Looks good. I already have the M40x which I'm pretty happy with.
It's easy to mod these with an MPOW to be wireless, too.
