From a branding perspective, I would strongly encourage you to adopt a logo which has "BBC" in it somewhere, as that will allow you greatest flexibility if you ever want to brand products, etc. See CCM for comparable practice.
And on that point, I'd recommend a very unique font style. Which may need to be purchased or licensed from the artist...which is fair and appropriate.
Some of the other logos are fun too, but I'm trying to think of what would work as your "signature" lasered into the bottom right corner of a slab side Series 5 body, for example...
