What does a complete setup cost, and how should the money split?

A brew ratio is the yield in the cup divided by the dry dose in the basket, and espresso conventionally runs 1:2: an 18 g dose producing 36 g of liquid in 25 to 30 seconds. Hitting that reliably takes a machine that holds temperature and a grinder fine enough to resist nine atmospheres of pressure. Here is what each budget realistically buys once both are counted.

How do you get from a new machine to a shot worth drinking?

Set the grinder so an 18 g dose yields 36 g in 25 to 30 seconds, and change nothing but the grind until the time lands. Faster than that means grind finer; slower means grind coarser. Once the time is stable, taste. Sour and thin is under-extracted, so grind finer again or raise the temperature. Bitter and drying is over-extracted, so grind coarser or lower it. One variable at a time, every time.

What kills home espresso machines?

Scale, not use. Calcium and magnesium in tap water deposit inside the boiler and on the heating element every time water is heated, insulating the element and restricting flow. The commonly cited target is roughly 50 to 100 ppm total hardness as CaCO3 with alkalinity near 40 ppm. Test yours with the water hardness calculator, and if it reads above about 120 ppm, treat the water rather than descaling more often.
