The two 23" monitors-one Dell and one Viewsonic I mentioned in my earlier post are both much cheaper than the 24". 24" screens seem, sadly, to be being replaced by 23" ones as this fits the 16:9 HD TV format better. Hence the 24" models are now much more expensive as this is no longer a standard size.
The two I mentioned retail at just over 200 British pounds. The Viewsonic has had a load of rave reviews here for it's great quality and value for money. I appreciate that £200 is slightly more than $200 but not a lot.
I'd check both of those out if I were you, Cheers, John
