Bumz_Rush, pity you don't like Stansted, as Ryanair will take you to Bergamo for a mere £64!
Is Gatwick any good? Same price from Easyjet for one way to Linate.
At Heathrow, BMI will take you one way for £137.
Otherwise Alitalia seem to have a two-way for about £90 inc! But I sympathize with you, when I see that they want a whopping £270 for one way!
Have a good trip!
