US & UK Keyboard issue

[James.s]

I'm just thinking about purchasing a new Logitech G15 Keyboard, I took a look at your site and found the G15 US version for £44.59 inc VAT, where as the UK version is £70.44 inc VAT, can someone tell me the differences between the 2 and the advantages and disadvantages of them?

The keyboard layout on the US one is the US keyboard layout.

The keyboard layout on the UK one is the UK keyboard layout.

I kinda knew that far already, but in what ways are they set out, Different Key formation?
