Miele
We have a Miele front loader. I've been cloth diapering for five years and I've never had issues with staining, stink, build-up, etc. I'd never heard about stripping diapers or the problems with HE washers and diapers until I started reading the diapering forum here... and I do use some synthetics (FuzziBunz, Knickernappies, some microfibre inserts, etc).
Miele machines are German made and built to last for 25 years (most washers and dryers today are built with a 10 year lifespan). Miele appliances are very quiet. The drier works mostly on airflow not heat, which is better for your clothes. You can program the washer to do anything. It has it's own heater so you can heat the water to the exact temperature you want. Ours goes to over 200 degrees Fahrenheit which will kill nearly anything.
My mom and my MIL have top loaders and I can't believe how much smaller their loads are. Our washer is tiny and it still does loads that are twice the size of what my MIL puts in her top loader.
All that said though, Miele stuff is REALLY expensive. I think we paid $4800 for the washer and drier. Our Miele dishwasher was $2500. Our Miele vacuum was originally $1200, but we scored it on sale. Now, those prices were in Canada, and they include tax, but Miele is expensive. I think it's worth it though.
