Showerthought: I spent $80 on a 'universal' power supply tester that was basically junk.

Bought it online for a quick bench check on some laptop bricks. The voltage readings were all over the place, like 2 volts off on a 19v line. Tried it on three known-good adapters, same junk results. Ended up just using my old multimeter like always. Anyone know a reliable brand for these, or are they all a waste of cash?

Universal" ones are always junk, learned that the hard way.

Actually have to disagree with you there, @dakota415. Found a universal one years ago that still works perfectly. It really depends on the brand, some are built way better than others. Just got lucky with that first purchase I guess. Throwing out all universal ones seems like missing out on some good options. The cheap ones are always junk, but a decent mid-priced one can last forever.
