Where are the experienced do it yourselfers sourcing the complete collection of o-rings for a rebuild?

Here in Parma, Italy there are at least 4 industrial resellers of O-rings.
You go there with the table for your Scubapro reg and for a few bucks you get all of them.
You can choose to have them in green Viton or other materials.
Here the table for the MK5, annotated with the commercial codes: https://scubaboard.com/community/attachments/mk5-annotated-pdf.456121/

Probably should included Grainger Industrial Supply. Brick and mortar but they are nationwide in the US. None near Napa though.
