At your listed budget, I don't believe a cheap VA mon will give you comparatively good video quality, and I see no reason why a cheap VA mon should be more durable than a more expensive IDTV. With a limited budget and if you don't really need recording right now, get a good IDTV first. When you need recording, get a Magic TV.
To use a monitor for TV purpose, ideally it should support 50Hz but some do not support it. It's also desirable to have 1080i support for diagnostic purpose, but again some monitors do not support it reasonably.
In case you need to use the TV as computer monitor, make sure it's 1920x1080 instead of 1366x768 (e.g. <$2000 Panasonic 24"), and make sure it has 1:1 pixel mode.
