I'm wanting to get an X3 and add a dro to it. I'm having trouble finding a suitable dro kit for it.

What kit would you recommend?

Also, does anybody know how much trouble they are to install?

Am I going to need another mill to tap holes in the table to mount the scales?

Thanks,

Instead of a kit I bought 3 readouts of the correct length for my mini mill and fitted them myself. Its not that hard and as you have a mill you can make any brackets.
Probably the most difficult part is drilling and tapping the cast iron.
If you get stuck show a picture of each axis and somone will help you place the DRO.
