Having gone over to a independent 4 jaw chuck for most of my work I think I need to upgrade my magnetic base for the dti. Currently I have an old school double clamp arrangement that works like a school science lab stand. I works but is fiddly to set up. I like the look of the eclipse e910 or similar. Any recommendations?

I have no idea what you get for that sort of money, but I have several (in a couple of sizes) of the £20-30 ones which look the same and are available from amazon and the auction sites. They work well for my purposes.
I keep the arm from one mounted on a tool post on top of my Taig lathe headstock with a DTI attached. It works extremely well for centring in the four jaw.
Edited for typo!

ArcEurotrade or the Dasqua 60 or 80 kg ones both work fine for me - and are much, much cheaper..
For lathe-work I tend to use either a bar-mount held in the toolpost, or occasionally one on a post bolted to the back of the cross-slide..

For truing up work in a four jaw, I go for the lever type indicator rather than the plunger dti.

It depends very much on what I'm trying to true up, and on which lathe.

Most of the time, I use a Finger clock for centering work in the 4 Jaw.
I gave away my Magnetic base with an "Adjustable" linkage.
the old non adjustable set up may be more slower to set up, but tends to be more rigid.
And what is the point of trying of trying to measure, if the indicator is able to move / deflect.?
If it does, you are effectively measuring with something hanging from a length of string; i e a very poor datum point.

I like the Noga dti stands, a lot better than the cheap knock off's. Another dti I have discovered new to me, is the electronic dti's found on the internet. They have a very low spring force, and have found them to be very reliable. I could possibly respring my Mitutoyo dti, but instead have opted for a 1um resolution digital indicator. It comes with 2 options for the backplate, a plain and the back mount option and a 30mm travel.
