I bought the Belkin one.
Comes with a 5" Link lead and power supply (Not that i need it)
There are several flavours, some with a few USB ports, some with more, and one with Fire wire.
I opted for the cheapest as I only wanted a couple of ports at the front for a USB stick, and to make sure that if I knocked my Tea over that it wouldnt flood the internals of my Mini! 😛
I spent a whole £5 at Morgan computers in the UK.
