Hi Chris,
I will try and get some photos sorted but if you need advice, PM me and we can talk about the install. I am In East Hampshire so If I am close, I would be happy to assist 
I went for the Glass scale on the Saddle essentially because it was cheaper at the time. I also considered it would be more robust over the travel distance on a GH1330.
The magnetic scales on the cross and compound slides were chosen because they are more compact than the equivalent glass scales. I used the 2 part scale mounts as that was all that was available at the time. I have since changed to their 'One Part' mounting kit and have to say, that is what I would use on future installs, reduces the install profile by around 5mm.
I used the budget readout head from Machine-DRO and this has proved more than adequate for the lathe. It has a Z0+Z1 combine facility which has proved very useful at times.
My primary reason for installing a DRO was that I have difficulty in reading small scale divisions caused by a visionary defect, ( I have Kerotaconus). Having a DRO on the lathe has transformed my machining ability. (Had one on the mill for ages!)

Graeme
