Are Sanwa anything like what they used to be? I seem to remember them having a
very good reputation for analog multimeters back in the day, but I was a kid back then and haven't heard anything since (haven't looked though). Do they still do their designs in house or is it just something by a Chinese firm with a famous name on it? Just about every product I have that's actually designed and
made in Japan has really impressed me, from my Toyota to the Sony PVM on my desk. Never had a Japanese piece of electronic test equipment though, for whatever reason they don't really seem to have penetrated that market in the west at the lower end consumer/hobbyist levels, apart from Hakko of course, but soldering irons are kind of a different beast.
EDIT: Some googling brought me to this model which looks like a higher end version of that PM300:
