Measuring ignition coils with a multimeter

The resistance spec for the ignition coils is 0.4-0.8 ohms. When I tried to measure it with my cheap Radio Shack multimeter, I get 0. I bought another $40 meter with 200 ohm accuracy of 0.1, and yet I get readings of up to 3 ohms just by touching the two leads together. I played with the idea of buying a Fluke but their tech support guys are uncertain as to whether their meters can accurately read such low values.

What brand of multimeters have members been able to accurately measure their ignition coil resistance with? If I can't find an affordable meter, I might go the trial-and-error method of determining which coils are bad.

I just have a generic digital multimeter. I get consistant reading with it. 0.8ohms on all coils.

While the Fluke probably rules, it might be overkill.
