Why? There are much better registrars. Randy and Sidney and I all represent much better CBs... why bother?
I work peripherally with an auditor that does work for Sidney's CB at our other plant and I would much rather have her. She's great.
The main reason I'm "stuck" with these guys is that this registrar is also our notified body for CE marking and senior management felt it was better to use them. I was also in favor of it until July.
When we consolidate the two plants' registrations then we will likely go with a more local CB. (part of the problem I think is that our chosen one is based in Europe and has no office or auditors based in the US). That's a couple of years out though... probably when the other plant is up for recertification.
