Elliot:
I prefer not wasting money on crap that does not perform to spec (read the 1-3 star reviews on the variacs noted).
Quality NOS variacs by General Radio and General Electric are plentiful in the same price range as the 2 noted Chinese variacs.
I do purchase inexpensive Chinese goods like sponges, rechargeable LED lights, disposable batteries, greeting cards et cetera but not items intended for reliability/long term use.
We still have USA plastic litter boxes that are in good shape @ 30+ years old (the made in China boxes rarely last longer than a year).
