Noga indicator holders are hard to beat. I purchased two of them on sale from Enco a year or two ago.
I agree with buying a low cost indicator. I have a cheap digital dial indicator from HF for use on my carriage stop on the lathe. It works well too. You can get fairly decent ones from eBay or places like Enco.
After awhile, you tend to accumulate them. For dial indicators, I have an assortment, but my most accurate were purchased used from eBay and are Mitutoyo 543-783B Absolute Digimatic Indicator. I also have several test indicators. Some low cost test indictors, which work well and several precision ones that I purchased used from eBay.
On calipers I have a Brown & Sharpe Twin-Cal IP67 digital one. I also like the Mitutoyo Absolute Scale one. I have several Starrett dial calipers (6" & 12") but hardly ever use them.
I picked up several dividers at a yard sale that I use a lot for lathe work. Not so much on the mill.
I have several micrometers. Brown & Sharpe, Starrett (1" & 2") mechanical. The one I use most is a Mitutoyo Digital Micrometer.
Some prefer dial for their instruments, I like digital.
Way oil for my Bridgeport. In the past I purchase Way oil by the gallon from
H&W Repair and Rebuild, but I plan to establish a purchase at Enco before they are merged into MSC.
#2 Way Oil (Mobil Vactra) This is typical for Bridgeport.
or
#4 Way Oil (Mobil Vactra) This is for larger mills.
and you might need
#10 Spindle Oil
On a vise, I purchased a new Kurt D688 on sale. I did not want to fight a poor vise, nor sacrifice accuracy. There are many good used ones on eBay and even Craigslist...Bridgeport, Kurt, etc.
