I have seen a lot of collisions from various vendors. Data, please. I have seen duplicates, too, but they were twenty years ago in the early 1990s, and they were from deliberate reproduction by cloners who were producing counterfeit boxes.

I have an Android phone I ordered from China that arrived a couple weeks ago which has a MAC address not present in the IEEE database, so it is likely that it can collide with some properly-registered device at some point in the future.

I checked here:

http://standards.ieee.org/develop/regauth/oui/oui.txt

The MAC address starts with d2:a1:42, which is not present.

That address has the "locally administered" bit set so at least they've done that right and aren't trampling on any address that will ever be assigned to somebody else.
