Ok, I wasn't going to add my list, but it's been a while since took a survey.  These are just the 500 series items and the 575s (because they look similar and are tube-based).  Many of the plugins have duplicates and some mods, but I didn't track them.  The Cordin plugins (ex-SRI) appear to be part of a manifold system for high speed camera triggers.  Cordin has no record of them (or didn't want to look); at least one other similar model exists/existed.
