I don't expect many will get excited about this drive as there's lots of good deals for external hard drives on here (I watch them, too and have been tempted by some) and yet this is the one I went for a couple of days ago. I love it : )
It offers everything I want in terms of feature set, speed, appearance (I got the graphite one), build quality, great reviews and good value, collect in store option (one hour after ordering), three year warranty, and very widely available at the moment. Yes I know there are 1TB drives around for an extra £10-!5 and sometimes portable ones for a similar price but they weren't quite what I was looking for.
Part of the same group you can also get them from Currys and Dixons at this price:
