Ultrashasp 2007WFP - worth of taking ? URGENT

Hi everyone!

I'm just about to buy slightly used Dell Ultrasharp 2007WFP (100 punds - about $200, excellent condition, with dvi cable) but I have no experience with everyday use of widescreen monitors. I am wondering if S-IPS screen is worth of buying (yeah...I've heard about the fact that Dell recently has started putting S-PVA istead but this one is unfortunately S-IPS) and if this monitor would be proper choice if I am going to mainly work with Office package, surf the net and watch movies in the alone evenings If it goes about games - I won't lie I don't like them - but only in my free time. I am also afraid if this model has sufficient gtg response time (16 gtg according to datasheet, but who knows how it really works... ).
I have to leave to see it in an hour so would be grateful for fast, but essential responses

I can also buy Gateway CRT VX1120 22" (old one ) so not to waste money and save up for some high-end Belinea LCD monitors based on S-PVA screen.
What would you do if you were in my shoes ?

Regards,
Dominik.

Thank for the answer :-)
