How about i550?

I know there's a Canon USB printer called the i450, not sure if they made an i550 or not, but not a bad name for it.

EDIT: There is a Canon i550...still a cool name. Besides, names do get re-used. Ask an older guy what a PS2 is and he will say an IBM. Ask anyone under the age of 27 and they'll say a Sony gaming console.
