I got my 20 inch LCD/TV/Monitor for $345 from Compusa on sale. Same Specs and used for 6 months.
Comment:
1. For similar products checking online you can find cheaper price after rebate.
2. 800x600 resolution is not good enough for PC! Be realistic, buy at least 27" LCD TV/Monitor or one which will give you at least 1280 x 720 pixels if you want to use it as a PC monitor. 800x600 on 20 inch screen you will only get large icons and you just waste this 20 inch screen. I'd buy 20+ inch LCD monitor for $200 or less, plus a $50 PC TV converter to get better result.
3. wait for a on sale season, you won't regret for the price
