I always use a meter when making a new coil, not only to confirm that the resistance is somewhere in the neighborhood of what I intended, but to also make sure I haven't caused a short. I use a meter like this, around $20:
I use one. It's pretty smart to have one. Some people who don't have an ohms meter have a Provari or some other mod with a read-out. Once you get used to rolling coils, you can pretty much do it right every time, but especially at first, you will want to make sure it's a viable coil before you put it on a REO and cause a short. Others may have a different opinion.
I have one of those little ohms meters ($20 give or take) from RTD Vapor AW Batteries that I use. I just put the atty on that and build a coil, then I check it before I put it on the REO.
Lately, though, my coils are pretty consistent and my confidence has risen, and I've built a few while my atty's still on the REO. That has turned out (knock on wood!!) fine so far.

That is what I have also. Use it to build my coil and meter before it goes on a REO. Best money ever spent to include in my RGA gear.
I have a couple meters, and I use to use them, but wrapping coils is like clockwork now. I dont bother checking anymore.
I use a multimeter. $5 from harbor freight. Can do ohms and volts on your batteries. Put an rba on the mod then take an ohm reading off the posts.
I use the same meter pretty inexpensive insurance, works well for checking bulk purchased atty's also before the DOA warranty expires.
The ohm meter mentioned above weighs approximately two-ounces with two, AAA batteries installed. At today's spot price of gold of $1613.80 per ounce that would make the cost of the ohm meter $3227.60, (plus shipping), probably a bit out of range of a normal vaper's budget... but a damn good deal if the federal government is buying it.
(They of course wouldn't buy one because, as they keep telling us, vaping is evil.)

Same here. If you think about it, with replacement springs @ $5 each, it's cheap insurance, not to mention, most of us would FREAK if we had to be without our REOs for any length of time. Hence, multiple REOs, obsessive ohm checks and battery checks.
It's a VERY good idea to check your batteries off the charger, and when you swap them out, to make sure you're not running them too low, or that they've come off the charger in a less than desirable condition. You can get a perfectly good one from Harbor Freight, that works well for checking batteries and attys/cartos for around $6.00.
Agree w/ getting a multimeter if on a budget plus you can use it around the house too. Seen too many tv programs of homeowners getting zapped during renos because they thought the power was off 
If it's not a necessity, it's at least a darned good idea. After you get one, you'll wonder how you ever lived without it.

I have an expensive Fluke multimeter from my old job just collecting dust.
That atty ohm meter in the picture and Sternos battery doohicky have relegated my multimeter back to the basement.
Must haves IMO.

+1 I build attach my coils using the same meter and then no added step to test them. AND.... after I build them and attach to REO I do a dryburn and/or torch of coil and wick, depending on the RBA, let it cool, and then put back on meter. Sometimes they need a little fiddling or tightening of post screws after the first cleaning/tempering heat is applied. (You can't torch or dryburn natural fibers. I've gone back to silica because my juices, all of the very few I use, gunk up coil and wick in a day so frequent cleaning and/or dryburns needed.

I must be paranoid! I have that box pictured - and a cheap multimeter from Harbor freight and a more expensive one (that self zeroes) from Sears. I always check before i screw them on anything, but since i only run REOs and a Silver Bullet - I am probably ok even if there is a short. My A7s will not seem to give me a reading at all on that black box though.
