Pressurised vs non-pressurised portafilter
Choose pressurised to start without a grinder; move to non-pressurised once you have a burr grinder and want better espresso.
The basket changes how forgiving your espresso is. A pressurised (dual-wall) basket builds pressure for you and tolerates pre-ground coffee; a non-pressurised (single-wall) basket relies on your grind and tamp for better-tasting results.
Many beginners start pressurised and switch later.
