Advice needed for £200 Monitor

Hello

Already made a post on the forums earlier about Graphics cards, the replys i got lead me onto thinking about getting a new monitor, orignal post http://www.tomshardware.co.uk/foru [...] _15_0.html

So as you can see from the very bottom of that link im looking to spend about £200 on a Monitor for that system, I've been scouting monitors for about 3 hours checking out the ones within my price range and there doesnt seem to be alot of variation, they all seem to be
"- Resolution: 1920x1080
- Contrast Ratio: 50000:1 or 20000:1 ... which are both equivellant to 1000:1, wtf lol?
- Brightness: 300cd/m² or 250
- Response Time: 5ms
- Viewing Angles (H/V): 170°/160°
- Colours: 16.7 Million
- Inputs: 1x Analogue & 1x DVI-D"

Seems the Dell's are getting the best reviews as far as 22" Monitors go.
I think i've got a shortlist of 3 Monitors now, all within my budget, all very good reviews for each.

Dell UltraSharp 2209WA 22" Widescreen LCD Monitor £200
found on http://www.overclockers.co.uk/show [...] =MO-032-DE

Dell SP2309W 23" Widescreen LCD Monitor £190
found on http://www.overclockers.co.uk/show [...] =MO-031-DE

Samsung P2250 22" Widescreen LCD Monitor £170
found on http://www.overclockers.co.uk/show [...] 49&subcat=

In a bid to find the best of the dells i checked their site, was very surprised to see the SP2309W 23" costing £175 ( http://accessories.euro.dell.com/s [...] sku=193757 ) from them and the UltraSharp 2209WA 22" coming in at £310 ( http://accessories.euro.dell.com/s [...] sku=198660 ), could anyone tell me why this is? mabye its just overclockers tempting me with a superb bargin?

also any monitors you feel are better than the 3 above please say

Thanks
