Dell 2007wfp is 8 ms GTG, for some bizarre reason Dell still quote the ISO reponse time just for that one screen but none of the others. Certainly quick enough for movies and I've played plenty of quick games on it. It's not as quick as the overdriven TN panels (the 2 ms ones) but as quick as anything else. The viewing angles of the S-IPS panel in the 2007wfp are the best around, far better than you'll get from any TN screen.
Also have a look at the OcUK 24" PVA screen which is excellent value.
