Cycle and deal status as of November 12, 2026. See the launch calendar →
The P1S lists at $549 and the Plus4 at $699 — $150 apart, so the Plus4 costs 27% more.
Per litre of build volume, that works out to $33 for the P1S versus $27 for the Plus4 — so the pricier Plus4 actually gives you more build space per dollar.
Neither is sold new any more, so we would not buy either at full price: the P1S has already been replaced by the P2S and the Plus4 has already been replaced by the Plus5. The fair comparison today is between their replacements.
