I'd recommend Dell monitors.
I know of least 6 on the go that haven't gave any problems over the last few years and my current one was a pretty good deal at the time of the offer >
Link The only current "bargain" offer i can see at the moment is this >
Dell ST2210 21.5 inch hdmi 1080 p monitor £127.20Also read the comments on the Dell link as there is other alternatives mentioned on there but i wouldn't go for the Benq one
I'd also say the LG should be a good monitor though if i had the choice between the Dell and the LG (same spec) i'd go for the Dell.
