Yup. Got a few of those laying around too. A couple of them are permanent fixtures on my alternator drive-stand. The ability to detect, quantify and display electrical phenomena has become so easy that even the least expensive tools can perform an order of magnitude better than the best-we-knew-how-to-do in 1970. The down-sides for these $low$ tools are mechanical robustness and environmental longevity. I've pitched perhaps a dozen over they years . . . and picked up replacements on the next trip to HF! Back when I was doing weekend seminars, my first question to the room was, "How many of you have multimeters?" I then made hand-outs to everyone who didn't hold up their hand! Barber Co Rural Fire is having a busy morning . . . fire-barn just east of my house emptied out about an hour ago. Heard radio responses from two other houses.

If you're not bound by any type-certification requirements, pick up something at the local auto parts store . . . or Amazon. https://tinyurl.com/2pzgcae3 These regulators share much in common with the electronic instruments market. Performing well is not difficult. Parts are so easy to manufacture that there's little or nothing to be gained by seeking 'cheap' production parts. These regulators have always been paired with ov management systems so the minuscule but non-zero risk is easily mitigated. Short answer is that there is little or no extra value to be secured by purchasing from legacy sources of parts for TC aircraft.
