Moniter Help

I'm looking to get a new moniter. I would like it to be at least 1920x1080, 60Hz, 22"+, IPS and under £170. I will be primarily gaming on it, but so long as the lag is not horrendeous, I vastly prefer quality of colour reproduction over response times, refresh rate etc. It must have either a DVI port or Display Port.
