I would suggest :
NCIX.com - Buy Samsung SyncMaster S24A850DW 24IN Widescreen LED Pls LCD Monitor 1920X1200 5ms 300CDM DVI DP Pivot - Samsung - LS24A850DW/ZA - in Canada
its a bit expensive, but is comparable to the dell monitor in viewing angles and colours. Investing in a dell ultra sharp is well worth your money in the long term, but if you're planning to spend a bit less and still get the same quality. I would suggest this.
(I had the monitor above for 2 months) Sold it because i didn't need such an expensive monitor as i don't do any graphic work
