Why don't you look on the store??? There's a 20" refurb on there right now for $599, which is still way too expensive in my opinion considering it's probably the older revision. You can almost buy two Dell 2007WFP for that price, which have the better more up-to-date panel. But if you have to have an ACD, the refurb store is an option. You could get a brand new one for $100 more though.
