Mixing old and new tech

[macguyverkevin]

Good day all

Well I'm sorting through and correcting a few things with my new-to-me ST3/Kohler 12RMO61 (not sure if that is a zero or an "o").
The Emico ammeters and output are destroyed, the DC ammeter is fogged unreadable, and the off/auto/test switch looks to be corroded a bit.

Rather than try to restore these components, and to integrate better remote alarming/controls, I stumbled across this Chinese-made digital control console on eBay

There are several sellers with the same/similar units as well as one without utility power monitoring (search "DC60D gen controller).

Has anybody seen these or better, installed one?

What else would be a good option without ridiculous cost associated with it?

Thanks in advance!
