Freecoms are very good. If you have a network but don't have a server/hub, you might want to consider the NAS version for about £20 more (Ebuyer), but other than that, your choice is a good one if the capacity is plenty for you. a 500GB version is about the same price as the 250GB NAS.

I own 2x 500GB external HD from Freecom. It was never really my intention to get 2 but I was so impressed with the first one, which I had for 8 months, I decided to get another one. I got them from here;
