Hi everyone, I am just about to pull the trigger on a new LCD monitor. Right now I have a Samsung 915N and just find it too small

I have narrowed it down to:
Samsung 226BW which is a 2ms 3000:1 TN 1680 x 1050 panel
NCIX.com - Buy Samsung SyncMaster 226BW 22IN Widescreen LCD Monitor Black 1680X1050 3000:1 2MS VGA DVI-D HDCP - LS22MEWSFV/XAA In Canada.
and the
Samsung 245B which is a 5ms 3000:1 TN 1900x1200 panel
NCIX.com - Buy Samsung SyncMaster 245B 24IN Widescreen Black LCD Monitor 1920X1200 3000:1 5MS VGA DVI HAS - LS24HUBCBQ/XAA In Canada.
IS the extra 2 inches worth $180 more?
The 24 lcd will be a "S" panel. The 22...who knows!
I'm leaning towards the 24...but don't know if I can justify the extra 180 bucks. That and it is a 24inch TN 6 bit panel and not a true 8bit panel.
All comments GREATLY appreciated!
