I had the Acu-Rite VUE on my last mill, was very nice and worked well. But at it's current price for the 3 axis mill version (around $1700), I would go with the Easson 12B (or C which is the same but horizontal format) which is 1/3 the price and has a great display. The scales should be fairly similar with regard to sizing, you can lookup the mounting dimensions. Alternatively you could get a 3 Axis EL700 with magnetic scales for the slightly less cost as the Acu-Rite VUE with 3 glass scales. I currently have the EL700 4 axis on my mill, very nice bright display with the more functions vs. Acu-Rite VUE. The only minor criticism I have of the EL700 is it uses a touch screen for the keys, so they can be a bit finicky at times and no positive click. If you go with glass scales than I would say go with the Easson 12B (they are about $500 through Aliexpress, $700 via domestic suppliers), if magnetic than consider the EL700.
