I saw that, but myescapehood.com isn't actually listed on Essex Industries' website as an approved distributor.
There are a couple of things - first the SKUs/PNs for the VRU and VRU+ seem to be restricted.
However, not restricted are PNs and SKUs associated with Essex Industries:
Self-Contained Unit (SCU)
Protective Breathing Equipment (PBE)
Emergency Passenger Oxygen System (EPOS)
All of those appear functionally similar (near as I can tell for the EPOS and SCU identical) to the VRU. You'll need an account with an aviation supply company to get them. I'm working through the list now. But haven't found pricing. I may have to call or email to inquire. It's okay, I could use an account with an aerospace supply company for high grade critical fasteners and high quality sheet metal for building my car anyways.
