I started home espresso with a Breville Barista Express. That served me well for about 4 years before I got tired of its limitations, especially in regards to grind uniformity and making adjustments for different roasts (ie temp, pressure, etc.). I stopped using the built in grinder in favor of an Atom 60, which led to a massive improvement and held me over until upgrading to a Profitec Pro 600.

Until I want something plumbed in, or really want to geek out over data from a Decent, I don't see much reason to upgrade any time soon.
