I have this for 5 years, and it sill makes excellent coffee... I'm a Starbucks snob, and this comes pretty close to replicating what they do at the store. roughly 1 tablespoon coffee to a cup of water, and grinding is a number 4 on the setting.
It can be loud while brewing, but that does not bother me. The carafe works great. I paid $150 for this new, which I thought was a lot of money. I think the MT600 is around $135
