Being completely serious.... I have been looking at tablets for the past week, pretty much every night. What I keep coming back to is this...
The Nexus 7 16GB is incredible value for money, even taking into account the cheap chinese tablets. If you are looking for a tablet and don't need masses of space over long periods of time (i.e. you go home and can swap your music/vid collection out), then get that. Nothing really comes close. (An alternative is the Samsung Galaxy Tab 2 7.0, but it really should be about £140 rather than £159 - the advantage is memory slot and a rear camera, but slightly less performance.)
The alternative I also keep thinking about is the Blackberry Playbook. IF you an get one cheap enough then it's a damn fine tablet for the money, if you can do without some apps like netflix/skype. Other than that it has an application for pretty much everything you could want, and is very very good quality. However - and here's the kicker - if it's coming close to the Nexus 7 price, then just opt for the Nexus. (EDIT: Skype IS coming to the playbook, along with the BB10 operating system and a whole host of other major apps).
The tablet you link to from OcUK, is not very good performance for games (especially 3D), has a very small battery, may not be compatible with some apps without doing some fettling etc.
I don't say the above things lightly. Don't blow your experience of tablets by getting a crappy one. Honestly... nothing really comes close to the nexus for outright performance/features (unless you need rear cam and memory slot) to the Nexus 7, in the 7 to 8" tablet space. Above 9" is where the chinese tablets start to become an option (imo), but you still have to make some sacrifices with those.
