Re build quality, if this is the new "designer streamlined" Miele without the orange button & simple dials then the drawer does feel a bit tacky. I had a chance to play with the older W613 and "designer" version (which tends to be =A350 less). Some parts that used to be metal are now plastic, the counterweights that used to be cast iron are concrete, the drum looks different.
Miele have tarted around with their vacuum cleaners too, but the old models did have a bit TOO clunky vacuum-end connectors. The latest S2210 (if that is the right code) is nicely lightweight, mainly through elimination of metal parts, the plastic appears identical. The downside is the superlight Miele put the tools on the hose, a dumb idea - but countered by the tiny case actually not holding the old
3.5L FJM bag but the larger 5.0L GN so economics are improved. The latest bags have 1 less per box (4 rather than 5 or 5 rather than 6) so the larger bag is distinctly beneficial.
I still say buy a machine with 5yr warranty, put the =A3400 saving over a 10yr warranty Miele in just about any fund - chances are you will not need to touch it until year 7 by which point it has a 50:50 chance of being about =A3300-800. At that point a) you will probably need to buy the Miele because everything will be scrap or b) devaluation will mean you will only be able to afford a manual tub & mangle for that money. Miele 5yr could be had for =A3449 May 2008, afterwards it hit =A3649 which as I recall is too close to the 10yr version (=A3829 last I looked).
If you buy a washer dryer, and have the space, buy 2 of them - sods law applies of course :-)
