I've got a samsung 2253bw, and I've got to say that it really depends on the guy who's watching. For example, I always notice the black that just isn't black on the edges when the film is in a different format from 16:9. Yet none of the people that come into my room seem to notice that, I remember pointing it out to once and they all said who cares, it's hardly noticeable. So black won't be really that black on a TN panel, at least for some people.
As for viewing angles, I also get bothered by these. If I'm watching family guy i won't bother to change the monitor's position, but for everything else it's either watch from a chair or spend 2 minutes adjusting the monitor so that I can see reasonably from my bed.
When I wanted to buy my monitor, I was really looking forward to the lenovo l220x, which is one of the few 22inches with full HD, S-pva panel and outstanding overall features. yet the 300 pounds price tag, compared to the 170 spent on the samsung had an important part when it came to deciding on a student budget.
At 300 pounds you can either go for probably the best 22" (the lenovo) or look for a decent 24" with a VA panel, i don't think it's worth spending that much on a TN
