I bought this one in October, and it's a great little vac. Cheapest end of the Miele range, usually $329. It does a great job, and is really quiet. I didn't buy the extra power head thingies, and am happy with it as is.
The link I posted is to Godfreys Miele page, where the C3 is also on special at $399, save $50.
In the famous Vacuum Repair Man AMA's on reddit, the repairer said he recommended Miele above all other brands.
