Harris Cyclery, the sponsor of the Sheldon Brown website, also carries them. I think Peter White is the importer and Harris still goes through him. I ordered from Harris (the Cyo Premium, not the Ixon) and the light arrived in 2 days. It'll take longer from overseas.

As for shaped beam vs. light blasters, I'm finding pedestrians react to my light just as much as the old high powered blinking light I used. Cyclists are always amazed at how I light up the road in front of me, and drivers just don't notice. I'm in NYC though, and the street lighting is everywhere. Mostly the lights are needed so you can be noticed. Occasionally I need the light to see the street in front of me so I don't hit potholes.
