I am looking to switch to WS soon. I want it to be a 21" or 22" WS. Unfortunately I am budget oriented too. What would you recommend for under $600? Me & Rafal bought for our dad a 22" iiyama ProLite E2200WSV. It is pretty cheap and looks really good even though my dad is still running a ti4200. What other displays could I look at in that price/performance area?
