I believe they are all the same not extremely accurate. although being able to read below 1ohm I would want something more accurate than a ohm reader. I personally use a fluke 77 at home and a calibrated fluke 85 III and feel safer. but I recommended one from fasttech to my sister so I'm not a ohm reader hater. just trust my fluke more.
That's the only one I'd bother ordering online. Most accurate out there, reading down to the thousandth of an ohm. The rest just measure to the hundredth.
That said, I bought a cheapie at a b&m cause I hate waiting.
