The best model for the money is this one:http://www1.euro.dell.com/content/topics/topic.aspx/emea/segments/dhs/minicat/new/upsell/inspiron-1764-n0076401?c=uk&cs=ukdhs1&l=en&s=dhs.
Sorry came up as dell outlet deal but it's actually from dell brand new so you also get quidco (should track at 5%)
5% off code ZC531$L2C$LJCF only if over £749, but for 3% off go to http://www.hotukdeals.com/item/479747/dell-student-business-epp-discount-.
Using the epp link comes down to £437 and after quidco cashback (which should be about £17) comes down to £420.
Obviously pay more if you need extra but this seems best value with hdmi, integrated camera and i3 core. Also this laptop has a 17.3" wled high definition screen (1600x900 resolution)
