If you've got the $150 to spare, and you use LJ heavily, get one yourself today.
I'm going to update the LJ commando instructions with addtitional pictures. That way there won't be any confusion about the layout.
If you look at the icon, you'll see that the beret is royal blue. Navy blue is easier to find, but less obviously blue. I'm trying to find a supplier for the United Nations light blue (more LH-ish), but I haven't had much luck.
A few possibilities:
The Battle Zone (they have light blue)
Hats4You (also have light blue)
