Depending on configuration, mounting, output type, etc, there are lots of options around $10 or less. Quick search:

I thought about 3D printing a pressure multiplexer to be driven by a stepper motor.

Imagine an 8 point ignition distributor.

You wouldn't have 8 real time pressure sensors, but I guess 1 second on each input should be enough for pressure to stabilize enough for measurement. So sampling all 8 inputs would take 8 seconds.

Commercially available but much more expensive than buying 7 extra sensors.

Should be a fun Arduino project.

Temp sensors are cheap, but pressure sensors are $15-20??each.
