Wow!, I have been thinking about this still and forgot that I posted this. I came to this sub-forum to ask about a very accurate reader and noticed that I posted a week ago. Not that I am getting old or anything...
Anyway, maybe a bump will get more viewers.

What's your budget?
My Fluke 8846A reads to 100,000th of an ohm (at +/-0.001 ohm accuracy). But it does cost a bit more than most DMM's, about $1,500.
The Fluke 289 reads to 1,000th of an ohm (at +/-0.15% accuracy). Don't know about their orher meters.Were you looking for a DMM or something for just reading coil/atty resistances? USA Ohm Meters claims +/-0.018 ohm accuracy on their coil/atty meters and they read to the 1,000th for lower resistance builds and, I think, to the 100th for higher resistances.

Thanks, but I was looking for the $100 model. Apparently, something keeps that 2nd digit pretty darn expensive. Actually, either would be great. I just see resistance readings a bit to far apart.
Thanks though.

I went through this and decided that my $15 black box was good enough and gave me two decimal places and it's easier to use. Having a background in electronics I really wanted to use a nice Fluke meter, but not so much that I will spend a ton on a "hobby" meter. Most entry-level meters ($100-200) just won't do what you want.
Anyway - good luck

Sorry, was editing my post to add the USA Ohm Meters mention when you replied. Were you looking for a DMM or an atty/coil meter? You mentioned DMM in your first post but I've seen that term used for coil resistance meters too.

USA Ohm Meters. Somehow my searches came across that they only went to the the 10th.
You're welcome.
Not sure if you're into soldering and stuff but that's a great meter for very little money.

What you want is THIS: Half Ohm milliohm adapter | Tech-thing electronics design
Inserts into any normal DMM with normal jack spacing, check the video out.

Interesting! Was there an accuracy spec somewhere? Didn't notice one in the video.
The page states "1% precise" so I'm going to have to assume that means within 1%, there is a 100 milliohm test resistor built in to the board, so you can check accuracy while it is installed in your meter. For the money, it's real nice.
I don't see any problem there. It would mean a 0.05 measured coil could be between 0.0495 and 0.0505

Jaanus has sent me a Half-Ohm which I'm hoping to receive next week. As per request he hasn't soldered the terminals, switch and battery holder yet and I'm planning on putting this in a tiny case with a 510 connector on top that can be plugged straight into a DMM.
I'll post the result when finished.

Above 1.00 ohms, they read to the hundredth of an ohm (X.XX), below that, they read to the thousandth (No decimal, just three digits).
I already have a cheapo black box ohm meter whose accuracy I've already tested, been debating getting one of their 3D printed ohm meters just because.
USA are saying their Ohm meters are accurate to 0.018 so on a 0.1 Ohm coil this means 18% error! How is that good?
