24" for 15k, I guess you have to wait for some more time to get 24" at that price point. Even though you get it, I bet it wont be as nice as the costlier ones - cause the manufacturers of LCD had mentioned that the prices of LCDs have been saturated - so the price drop will be nominal and no huge/ big price drop.
So you better go for SP2208WFP or wait for S2409W/S2309 as I said earlier. The reason for me insisting on DELL is I've gone crazy after owning the SP2208WFP (all because of its beautiful GLOSSY panel).
And about that resolution problem - you might have to sacrifice few games or get a regular 24" 16:10 monitor.
