Short answer: under $300 the upgrade worth paying for is a non-pressurized basket and a real steam wand, because those are the two parts that let you control the shot rather than have it controlled for you. The recipe does not change: the National Coffee Association describes espresso as high pressure through a fine grind in about 20 to 30 seconds at a 1:2 ratio (NCA, espresso).
A non-pressurized basket only helps if your grinder can hold a fine setting, so treat the basket and the grinder as a single purchase decision.
What to require in a sub $300 machine
| What to check | Why it changes the cup | What to require |
|---|---|---|
| Non-pressurized basket option | It hands the resistance back to your grind, which is where control lives. | A standard basket included or available |
| A real steam wand | A bare wand textures milk; a frothing aid injects air for you. | An unaided wand if you want to learn |
| Temperature behavior | The NCA specifies nearly boiling water; a thermoblock has to recover between shot and steam. | A stated warm up and recovery routine |
| Portafilter size | Standard sizes have accessories and baskets. | A common size with baskets and tampers available |
| Pressure gauge or OPV | Tells you whether the puck is the problem. | A gauge if you plan to diagnose shots |
| Backflush capability | Group cleanliness affects taste over time. | A stated cleaning procedure |

What the machine is actually trying to do
The National Coffee Association describes espresso as high pressure forcing nearly boiling water through finely ground coffee in about 20 to 30 seconds, at a ratio of 1 gram of dry coffee to 2 grams of liquid espresso (NCA, espresso). Every part of a machine is in service of those three things: pressure, temperature and time. A feature that does not touch one of them is a convenience feature.
Pressurized against non-pressurized baskets
A pressurized basket has a restrictor that generates back pressure regardless of your grind. It makes bad coffee drinkable and good coffee ordinary. A standard basket does none of that work for you, which means the 20 to 30 second window the NCA describes becomes something you hit with grind size instead of something the hardware fakes.
The honest test is whether you own a grinder that can move in small steps at the fine end. If not, keep the pressurized basket until you do.
The grinder outranks the machine at this budget
The grinder decides whether the machine can work at all. The NCA puts espresso at a fine grind, like table salt, and recommends burr grinders because a blade grinder cannot ensure a consistent grind (NCA, espresso, NCA, pour over). A machine cannot hold a 20 to 30 second shot if the puck's resistance changes every time you grind, so at the lower budgets the grinder is the better place to put the next dollar.

FAQ
Should I use a pressurized or non-pressurized basket?
Use a non-pressurized basket only if your grinder can hold a fine setting and adjust in small steps. A pressurized basket creates resistance for you, which hides grind problems but also removes your control over the 20 to 30 second shot.
How long should an espresso shot take?
The NCA describes espresso as taking about 20 to 30 seconds, with high pressure forcing nearly boiling water through finely ground coffee. If your shot runs much faster or slower, the grind is usually what moved.
What espresso ratio should I use?
The NCA publishes 1 gram of dry coffee to 2 grams of liquid espresso, weighed rather than measured by volume. That is why a scale is on the NCA's espresso equipment list.
