In reply to Stani49:
That's only the cost if you're being guided. There are no peak fees in the alps. If you get a Swiss guide in Zermatt, it'll cost you about 1300 euros or so. Booking a week's climbing holiday with a guide (specfically to climb the Matterhorn) will probably cost a couple of grand if it's just you.
Also I assume you know that the Hornli Hut is being refurbished this year, so you might want t0 look at the Italian side.
Out of vague interest, who told you it cost £960?
