How much should I spend on my first espresso machine?

Under $300 gets you pressurized portafilter machines (Breville Bambino, De'Longhi Stilosa) that are forgiving but limit growth. The $400-700 sweet spot (Breville Barista Express, Gaggia Classic Pro) offers unpressurized baskets, PID temperature control, and the ability to dial in real espresso. Spending under $200 on an espresso machine usually leads to disappointment.
