My results for finding non-widescreen LCD monitors that don't suck and don't cost over $400:
19" 1280x1024 Samsung 943BX from Dell - best one I've found so far
943BX Specifications from Samsung's website
19" 1280x1024 Samsung 943N - has no DVI connector
19" 1280x1024 Samsung 943T from Dell - 10000:1 dynamic contrast ratio?! Nevermind, its an old monitor (25ms response time)
