I went for the SMI50C16GB at £449 from Currys including delivery. I installed it myself over last weekend but that was interrupted by haeing to go and sit through some awful football match. They would have fitted it for £90 and taken the old one away for £19.99 but I managed to do all that myself and felt better for it. I was replacing an existing semi-intergrated old Hotpoint model so the water suply and drain connections were already there. I had to relieve the opening on one side of the door but that had never been right anyway. When the Hotpoint was originally installed the fitter buggered up the door so I still had the replacement one that had never been fitted. We also looked at a Miele but the reviews all said that the cycle time was a bit too long. Besides, the Bosch was about £40 cheaper.
The only other problem was cleaning out all the debris and broken glass from under the units. The spiders were not too big.
