Just found this system a moment ago - seems quite a good price with the 22" Monitor.
You can get it cheaper with the 20" Screen, but it says this will possibly delay your order by 45 days!!!
Also you have to add the Logitech Cordless Desktop EX110 and select Mouse Included in Wireless Keyboard and Mouse option [subtract £17.62]to get this price.
