Miele are great, we have the 1400 rpm (now 1600 see below!) stainless steel one which gets a daily beating as we do a lot of sports so feed it with clothes daily once during weekdays and on weekends up to 3 times a day. It's been going now for 2 years, and clothes come out brilliant, definately a mile better than my parent's now aging Zanussi.
It did arrive with a PCB fault (apparently known by Miele that a few of them had this fault) but they offered us a new one to replace, or a new PCB with a free 1600rpm upgrade (we picked the free 1600rpm upgrade). It also has a 10 year guarantee.
The only thing which was missing which did kind of irk me as it was a £1300 washing machine is it didn't have delayed start.
If you do go second hand make sure it has warranty just in case!
