What ever happened to good ol' multimeters? One device that does a hell of a lot more than just an ohm-meter, and usually more accurate too...?
From what I understand, the inexpensive multimeters that most people have are terrible at the low resistances we are measuring. The internal resistance of the meter itself starts to come into play, as does that of the wire between the meter and the probes (as well as the probes themselves).
Four terminal sensing (Four-terminal sensing - Wikipedia, the free encyclopedia) is often used to overcome some of these limitations.

Best autocorrect I've seen in a while..Sorry bud!
