TDK USB Adapter

I've noticed on a few sites that there are 2 versions of the TDK USB adapter

1) TDK USB Adapter - upto 100m range
2) TDK USB Go-Blue Adapter + - upto 250m range

but the TDK website http://www.tdksystems.com/products/intro.asp?id=4 only
has the first one advertised.

Can anyone shed some light on this.

And anyone tell me where I can get the go blue version from.
Does E-buyer sell the go-blue one because thats the picture it advertises.
