I wouldn't own an LCD screen exept for LAN gaming myself. I use a 19" KDS VS. The wieght and portability factor is the onlt readon to own one IMO.
As far as returns, Tiger Direct is good, New Egg is good, Mwave.com is good, xoxide is awesome, Crazypc.com is awesome, justdeals.com blows in everything customer service related, Nexfan.com has poor service.
The first 5 retailors listed there will take good care of you should something be defective. You should never order a very high priced item from somewhere unknown, Speaking from experiance, just because it's listed on pricewatch don't make it an established company (got ripped off for $1400) Thank God for fraud protection on the credit card baby.
