If you had your choice which one would you get. I have looked at most of the models and while the hornady seems really popular right now i dont like that you can only check loaded rounds. I already have a Forster trimmer so i would have the pilots for one of them. The sinclair one looks really nice as well.
The rcbs one looks like some crazy contraption and the redding only measures case necks. Tell me your choice and why
 
I'm not real happy with my RCBS gauge. It works for cases and bullet runout but the aluminum block that rests the case on is starting to get worn and giving in accurate readings.
 
im not a fan of the hornady one. I think its flawed. Ive been using the Sinclair. its decent and does the job. its interesting to see how good or bad your set up is doin.
 
NECO; it will measure just about anything you want and does it very well......if you're a FCSA member they give you a 20% discount to boot.
 
The Sinclair works great for me. I have the analog version and it's good to see the needle moving. Easy to tell the amount of run out.
 
I have the Sinclair, Neco , 21th Century and the Accuracy One concentricity gauges.
Without a doubt the Accuracy One is the best. It has many very useful features that simply make it the
easiest and most convenient to use. One handed operation, easy to adjust sliding bases, easy to adjust indicator screw,
I could go on. But, it is very Expensive. $280 minus indicator ( which you could purchase from Enco, a lot cheaper).
It can be viewed at bullettipping .com.

Im trying to keep it in the $100 range for now. I'm split between the Sinclair or the Forster. Both are on sale currently 88 plus shopping for the Sinclair and 78 for the Forster from midway
 
I have several. Now days I only use my Accuracy One. Very easy and fast to use.

My Sinclair and NECO gauges are gathering dust.
 
my hornady concentricity gauge has about .003" of play in it. That makes it very difficult to get accurate readings. I since have started using wilson seater dies, so I don't use the concentricity gauge any more or I would find a different one.
 
I have both the hornady and the Sinclair. And I am glad I have both.
Can't check run-out on empty case necks on the hornady.
If I could only have 1, the Sinclair would do it.
 
Does anyone know if the Accuracy One gauges are available online somewhere. My friend was asking.
 
I have, and have used nearly all of the makes and models described on here so far; Sinclair (couple of versions), NECO, Forster and some others. Never heard of the Accuracy One, but in reviewing the video on 6mmBR.com, I think I'm about to order one. Seems to nicely answer most of the complaints I've had with the others and looks like a rock solid unit.
 
You will love it.
Starting with the one handed operation feature, no more holding the cartridge down and trying to
spin it at the same time. Place the cartridge on the extremely easy to adjust ( magnetic base) rollers, swing the arm down
and spin away. The design keeps the cartridge in place and you turn the wheel with one hand.
Also, the adjustment screw for the indicator is great. No more trying to hold the cartridge in place and
adjust the indicator to the proper height at the same time (PITA). Place the cartridge in position, make a rough adjustment
and make the final adjustment with the screw. It's beautiful. Also it's heavy enough that with its rubber feet to
stay in place during use.
It is very Expensive but to some people it may be worth it.
 
Another happy Sinclair user! Like it better than Hornady, Bonanza and RCBS. Have not tried any others. Lightman
