NEC SuperBright Diamondtron monitors are by far the best looking screens I've seen.

They're also the only monitors I've seen where you don't have to turn the brightness all the way up for it to look right next to an LCD. The 22" version is $569, though.
The only way you could get a really good 21" screen for $250-$350 would be a refurbished one.
http://www.accurateit.com/ is a good place -- I live right next to the warehouse. You can get a good Diamondtron or Trinitron 21" for as low as $225.
...oops, looks like that was already mentioned...
