Cheapest place to pick up a new windscreen

[ben306]

After a trip to Le Mans, Ive come back with a cracked windscreen on the hdi.

After the cheapest place that do them with the rain sensor.

So far have £95+VAT without, £155+VAT with. Not sure whats involved to swap from the sensor to the standard intermitent if I was to go with a standard screen.

Any info much appreciated.
