GreyWoolfe,
I asked a related question in the other Aneng thread last month and evava did some test measurements. They're not quite as low as you want to go, but look promising. Have a gander at https://www.eevblog.com/forum/testgear/new-aneng-multimeter/msg1276004/#msg1276004 to see if it might fit your needs.

My AN8008 measures those sorts of resistances just as well as my Fluke 87V does. In fact, you have to put the 87V into hi-res mode to match the 10 milli-ohm resolution of the AN8008. The only downside of the AN8008 is no relative mode, so you have to account for the resistance of the test leads manually. And the 87V is a touch faster to auto-range, but for your use, you could always go for manual ranging.
Of the range of tests I just did, the two meters agreed within a couple of counts of each other. No complaints from me :-+
Oh, and the Fluke 101 is only 0.1 ohm resolution...

I see what you posted. 1 \$\Omega\$ resistor measured .98 \$\Omega\$. That is just what I need. 15-18 \$\Omega\$ is good, 30 \$\Omega\$ is bad, according to the service manual. I think it will work just fine. Mark, I don't believe relative mode is necessary for my use. The Velleman doesn't have it and the measurements are very close between it and my GW Instek GDM 8251A. The Velleman is manual ranging so no big deal to put the Aneng in manual mode. The 30 second wait to stabilize is no big deal, I can turn it on and remove the FRU and by the time it's out, the meter will be good enough. I will grab one and if I like it, I will grab another. I have a couple more sets of the Brymen leads from Frankie coming, I will use those instead of what the meter comes with, which will also help.

For this kind of measurements it might be advisable to clean (the metal of) your test probes with acetone and then with contact spray, I found low value resistances to become quite a lot more consistent. I have a bargraph meter too and you can definitely tell the difference (btw continuity on a fast meter is a good indicator of probe cleansiness too).

Hi, I just bought both models an8008 and an8002 I think both are a good complement. Modify the an8008 eeprom to add the temperature measurement function.
Direction 0xAD = 0x13 and 0xBD = 0x15 to add the functions ° C and ° F respectively in the mV position.
Copy calibration data from an8002 to an8008, addresses from 0x0B to 0x0F
Both measure the same temperature now
