no one else has replied so Ill have a bash...
this is an e61 machine but it has no heat exchanger. This means it will not be as effective or efficient for steaming milk as a HX machine such as isomac tea or millenium.
depends on what you normally drink, for straight shots the Zaffiro is highly desireable. Maintenance issues would be similar to any e61 as they all essentially use the same parts.
I would probably see how much you could get a HX for, someone said the expobar office can be had for $1300. Isomac teas retail around $2k, or the one Id like but couldnt justify is an ECM Giotto premium which is closer to 2.5k.
Once you get up there the Rancilio S24s becomes an option at 2200
