My goodness the price on these now days! it’s been a long while since I purchased mine but they have doubled…. A quick glance says the one on eBay might be the best option for new. Good luck!

There are a lot of counterfeit Interapids on Ebay, If the price looks to good to be true, It probably is. I would buy it from MSC or somewhere like it.
 
I got ALL of these for the price of an Interapid:

You need to know…it doesn’t matter to the real machinists but the one above spins backwards (meaning counterclockwise) and the one with a V operates in a normal clockwise. One would think it would work but after the third barrel I indicated and after moving the barrel the wrong direction…I had a near miss with almost throwing it across the shop. I went to the V and I agree with the guys above but I’d just soon not have one that works backwards…my simpleton mind just couldn’t.

I do like mine…it’s the difference between a nice Swiss watch versus a Timex. Sure the Timex will work but man is the Swiss watch nice.
 
I agree, some of the prices of good indicators will give ya sticker shock
I really like my Federal Testmasters Yellow Face .0001" for the price
But Do recommend a long stylus with whatever brand you choose.

I like the Mitytoyo 513 series because I can reach into a rough drilled hole and indicate the throat in my Benchrest Chambers without such a long stylus.

Good choice...to the OP
Heres one of those on Ebay.....good price
 
Long Island Indicator has a page that all of you should read. It is a list of the best to the worst indicators you can buy. They have had all of them apart and know what they are all about in their inner workings. They also tell you which ones can be repaired and which ones still have parts available for them, And also which ones do and don't make economic sense to rebuild.

Some of you may be surprised to find out your prized indicator is a "Pizza Ship" in disguise.
 
Actually, if price were not in the equation
I like earlier Brown & Sharpe
I don't see that brand in the Comparison though? Strange, (same as Tesa is why I guess?)
I like the looks of those P- Line gauges
But then looked them up
I am NOT paying $600 for an indicator, lol, as nice as they may be.

Interapid: where do you find the "V" ? I'm thinking the "V" is in place of the "B"....? 312B-15 in the one shown under the part number pictured by Alfred
 
I'm no expert and I know we are only measuring relative movements. These indicators need a 12 degree angle to read correctly, with the vertical you're going to be at 90 degrees give or take.

I own the regular one that runs the dial "backwards" and don't have a problem with it.
