It's readily available from any TD, justs ask for the ultimate version with 2656 engraved on the back.
There are 3 versions - the swiss version, the Asian movement on steel bracelet (some argue it's not ultimate, and bracelet is not interchangeable with the ultimate) and the Asian movement ultimate.
The last can be had for under 500 and is the best bang for buck!
The one shown is it the Asian movement ultimate? How reliable is the movement over the long haul btw? Thanks for this review, I've been looking for something like this for a while.
