Was shopping around for one of these, and came across this last night. Cheapest I can find it anywhere.
It's about ~$700 AU shipped at 3LT and about ~$752 AU shipped at B&H.
Note: sale ends mid January with no specified date, 16th expiry is assumed and may be a bit off, will correct when I find out more.
I have one of these. Got it immediately after release abroad. Used for about a week before a leg broke. The locking mechanism's on the legs are not fantastic - its basically a plastic mechanism hidden under the very nice finished nobs on the legs. It is a beautiful tripod, but at $598 I wouldn't recommend it. Some of the cheaper alternatives are, IMO, just as good.
