I cannot offer any direct info but I too am considering fitting igaging DROs to my mill (not a Tom Senior).
These scales work on the same principle as cheap Chinese calipers and as such ‘can’ suffer from swarf ingress and of coarse limited resolution . The big advantage with having a separate display is that the scale can be sited out of harms way.
I hacked two 6″ calipers and fitted them to a small mill last year, they transformed the use of the machine but having to mount them so the display was readable meant they required frequent dismantling to clean them. I don’t think the same would apply to a remote display setup.
One question that might be worth asking of igaging relates to ‘auto power off’ and whether the last reading is stored when off.
The calipers I used switched off the display after 10 minutes or so. When I switched the caliper back on the display showed the value it had when it turned off. If I went away from a job for a cup of tea I knew I could just carry on from where I left off. The new calipers I have also switch themselves off, BUT, they always initialise to zero. I don’t know whether the igaging scales have auto off but it would be worth asking before you buy.
