Just wanted to mention that the supply from Element 14 in Australia is outstanding. I put in an order for 2x model B's two weeks ago and received them both (512mb model) last thursday ... approx. an 8 day wait.
I actually got my Pi from Element 14 Singapore in just two days. I’m surprised when I got the package. Maybe it's because the demand in my area (Hong Kong) is low.
This mirrors my experience for Element 14 in the UK; ordered on the 11th and received on the 18th.
The supply has gotten really bad again since the switchover to 512MB base RAM has been made public knowledge. You ordered yours just in time.
Apparently Element14 does not ship to Japan. Even if you select "others" in the first country selection list. I have no idea why...
