Find a cheaper pressure sensor than the MPXV5100DP (from a reputable distributor)

Currently our design is provisioned to use this sensor:

Octopart page with list of distributors: https://octopart.com/mpxv5100dp-freescale+semiconductor-800769 -- Average price is $12.81

Even when sourced from China, this pressure sensor is very expensive. This will impact our BOM cost.

We want to find a sensor that meets these specificaitons:

Measures differential pressure (these are cheaper than vacuum sensors, in practice).
It should have two barbed tube fittings on it (we will connect one to the vacuum system, and leave the other one open)
Measures up to 1 atmosphere (~100 kPa or 14.7 psi)
Same form-factor as the one in the picture, ideally, but even a through-hole version like the MPX5100DP would be OK.

Assigning this to @itsmefelix- .. if you have any questions as to whether a particular sensor will work, post them here and @vonnieda and I can have a look.
