Newegg has Asus' newer 23" budget IPS for $185-http://www.newegg.com/Product/Product.aspx?Item=N82E16824236288&Tpk=vs239h
they also have the VG23AH which is also 23" but its about $100 more and has slightly better specs and does passive 3D.http://www.newegg.com/Product/Product.aspx?Item=N82E16824236262&Tpk=vg23ah
the PA248Q as recommended above is also a very good option if you don't mind the fact its a 16:10 res rather than 16:9. I personally like 16:9 for gaming just because of the wider FOV you get with that aspect ratio, so I my self just bought the VG23AH. Jeff, hows the matte finish on the PA248Q I heard its not as thick and grainy as the past IPS panels have been? I almost got it because I just left a 23.6", but I was afraid of the matte finish
(the VG23AH is semi-glossy).
