Not an owner, but will say Breville is making steps in the right direction and it started with that machine. Their offerings before the Barista Express were all about form and very little about function, but that has changed. They seem to be listening to what coffee consumers want/expect now more than ever.
Regarding the machine, it has some nice features. Nice conical burr grinder on the side. Properly designed group/portafilter as well as having the choice of single or dual wall baskets. My only fault with it would be the thermoblock, which is what flash heats the water as it passes through. Thermoblocks heat up quickly, but usually don't offer consistent brew temperature or pressure when compared to a boiler.
For the $ it's a pretty good deal when compared to what's currently on the mark. Breville's next step up is more than twice what you want to spend now, so the machine in question may be a good starting point for you.
