Advice Needed: 3 Axis DRO Kit For SX3 Milling Machine

I am thinking of buying one of these 3 axis DRO kits for my SX3 milling machine...

3-axis digital readout for mill milling machine (complete DRO kit!) | eBay

Obviously there will be no machine specific instructions with this kit so i am looking for advice on the best way to mount it all.

Has anyone here got this or a similar kit fitted to an SX3 machine? If so i would appreciate some photos of how it has been mounted, brackets etc? What 3 sizes of scales are recommended for the SX3 machine?

Any other advice regarding fitting this kit to the SX3 machine would be great.

Thanks
Darren
