For what you want, you are not prepared to spend enough.
For 200 pounds or do you will get a TN panel: Fast, but poor colours.
What you need is a PVA or even IPS panel, but these are more expensive.
Have a look here or Google 'Monitor panel types'.
I love my VP930B... just a little old but it's a true 8bit panel. Ghosting isn't really present.
Still, you better with a 32 inch good quality TV with 120Hz and 1080p options. The thing is you need to find a good model for black levels too. Don`t expect to find one for 500$... maybe 1100$, for a 32 inches.
