There are plenty of very good TFT's @ the money your looking at.

Dell TFT's are some of the best at the moment, Phillips, Samsung, Viewsonic are a close 2nd. Avoid the Sony`s unless you plan to spend megabucks.

Try to buy at the top limit of your cash. 8ms or less and something you like the look of, after all your sitting looking at the thing all day !

Shop around for the best deals. Some places offer a dead pixel service (they check it, so you don`t get any).

Ebay is a very good source of them, just make sure to buy from a company not a private seller.
