I used a small Breville espresso machine for two years and liked the brand. I wanted to upgrade so decided to stay with Breville and found the BES900 Dual Boiler. It solved the problem of having to share a heating system between extraction and frothing that I had with the small espresso maker.
It also had a lot of extra features including a slow extraction, a larger tank with a built in filter and the ability to change the settings, for example the default temperature of the heated water.
