Robert, The Titanium is certainly an advance on the Brera in a lot of ways. I know a lot of people are concerned about the metal/vs ceramic burrs, but keep in mind this machine is grinding on a shot by shot basis, and brewing in between. The burrs aren't working hard enough for a long enough time to really heat up to make a difference. In that price range though, you really cannot find a machine with more options than the Titanium. Even going above $1000 a lot of the machines don't offer everything that the Titanium does. If you are worried about the durability of this machine, take heart in that it was designed to be able to be used in a light commercial environment like an Office or a waiting room. Home use is a vacation for this machine! While not interchangeable, the brew groups are actually very similar, and very reliable. We have put both machines through the ringer here, and we haven't had our own machines fail in any area yet.
