Well I am aware of this monitor, but it has really sucky image quality. It is definately below my minimum standards with 1.8 average gamma and washed out colors. These IPS monitors are really not bad for gaming, the response time difference between the Dell and the TN ones are irrelevant. It is only the higher refresh rate, the sync techs and the back-light strobbing that make a difference.
The LG 24GM77 is your best option if you cannot support sync techs, and it is probably worth it to import it from another european country if it is not available in UK.
Boarderline qualifiable is the BenQ XL2430T, although it is not still as good as the LG.

The necessary changes it need to display a proper image: " We used the Standard profile and set brightness to 39, Gamma to 4, red colour temperature to 100 and green and blue to 93. You might want to turn on Instant Mode as well to reduce input lag. With these settings, we got much more accurate colours: Delta E came down to 2.3, gamma to 2.3 (although it was too high at each end of the scale, meaning blocked-up blacks and blown-out whites) and colour temperature to 6500 K."
An even cheaper choice is the BenQ XL2411Z, with blur reduction and acceptable image quality once you make the changes below.

"Use the "Standard" picture mode. Next, set the brightness to 40 to get a more comfortable 200 cd/m² then select gamma profile "Gamma 4". Finally, set the colour temperature to "User" mode with red at 100, green at 95 and blue at 90. This helps calm things down, bringing the average Delta E to 2.1 and the colour temperature 6660 K, while balancing out the gamma at an average 2.3."
