venji - no problem. 13 pounds huh? Isn't that like 6,000 US? ;)
You might see if the us sites do international shipping. I cant see how the gun would work any different. Might be cheaper for you to pay in american dollars plus shipping.

Twesterm - I think I found an answer for you

You're going to have to explain what's going on there because it's way too small for me to tell.

-edit-

Ok, I think I see.  Is that the dongle attached to the bottom of the gun?  So now I have to wonder, does the wireless nunch or the perfect shot come with the extension cord or is that something I have to buy seperately? 

Yeah, the dongle is attached to the bottom of the gun. What extension cord are you talking about?

Wouldn't a wire need to go through the shaft of the gun to reach the remote? Or does something plug into the gun where the remote connects so you plug the nunchuck in at the bottom?

-edit-

Just read the website and it does just plug into the bottom.  That's pretty cool.  I might actually check this out if I can fiddle with the RE4 and Metroid control schemes. 

I got two of these back in December as well. They are pretty awesome especially for Ghost Squad and House of the Dead.

Exactly. The remote slips into a connection that is on the top of the gun in the back. That activates the port at the bottom of the jack to give power to the nunchuck. No extra cables needed. Stick the remote into the gun, slap the dongle onto the bottom of the gun, and you're set.

Man, UC would have been a lot more comfortable with a gun.

How can you properly use the gun in a shooter?
You need to walk and turn -> Nunchuck
Sidestep? Also with nunchuck?

If you read the above posts you will learn that the nunchuck plugs into the bottom of the gun. No problem.
