I was looking for the best one in the sub-£400 price range and so far, the winner is: iiyama ProLITE b2888UHSU
28 Inch Screen
Uber Sturdy Height-Adjustable Stand
All this for a cool £380
And don't think that iiyama is a "budget-brand" I have one at my desk at work and it's totes amaze-balls. The build-quality is really good like a Japanese motorbike, no surprise iiyama is Japanese too!
Let's see if anyone can find a better deal for less than 400 quid
... and the ones that won't
