any advice for a 3 axis DRO for my mill?

[Dr Stan]

I bought a 3 axis Sinpo off EBay for my Fray #7 mill and have been quite happy with it.  As you can see on the mill it has the traditional X and Y axis with a third one which can be parallel or set at an angle to the X axis.




I also have a Shooting Star on my Logan lathe.  Good product, but I was not impressed with their customer service.

BTW, this pic was taken before I mounted the DRO on the mill.
