Yeah, ordering directly through Asmus is always quickest. (Plus, it has the added advantage of making sure more of the money goes directly to support the company.) For most figures they have a pretty quick turn-around. Off the top of my head ... maybe six months or so from pre-order to shipping? Does that sound right? (Add a month or so if you order through Sideshow. Maybe two more months if you go through BBTS.)
It varies from figure to figure, of course. But it's typically a lot faster than Hot Toys or (shudder) ThreeZero where you can be waiting a year or more. Sometimes it's REALLY quick. Just a couple of months. I remember Theoden and Arwen being really fast between announcement and shipping.
This Crown Gandalf is a whole different animal, though. All the hairing is super labor intensive and meticulous. This is uncharted territory for them, so I'm cutting them all the slack in the world when it comes to his timelines.
