Hugo,
If you want a good quality product with good backup, solid engineering and no messing around then don't piss about; just buy a Miele.
There are 5 and 10 year warranties, excellent service from the manufacturer which will be seldom needed.
The question is then simply to find the cheapest deal. You pay your money and the manufacturer delivers directly in most cases (except perhaps JL).
I have three Miele white goods appliances with in excess of 25 machine years of operation. The washer, which is the oldest continues to perform as faultlessly as it did on day one. So do the others.
If you want to tit around with brushes, belts, drums, gaskets and all the rest of it, then buy any of the products at a price point of 60% of Miele.
One caveat is that the washers are heavy and are a two person move. Almost at the point where you might need to submit a building notice to your local authority to get floor loading checked :-)
