So it's a standard Hex Naga that uses yellow LEDs? What? Why would anyone want it yellow? I was considering a Naga, but I definitely would not get a yellow one. I currently use a Lechasis and I don't know if I'll buy any more Razer mice because of how small they are, I have really small hands and even for me their mice are a bit too small.
As for the mouse pad, if it's available locally I'd buy it.
I'm certainly not paying for any of Razer's "limited edition" prices though. I also highly advise staying away from their keyboards, you don't get what you pay for with those, you pay for its appearance which degrades and you pay for the name.
