DRO for 2013 Shopmaster Patriot VFD

I have a never used Patriot that I wish to add a DRO system. I called Chicago Lathe this week and was informed that they no longer provide after sale DRO installation setups and they couldn't provide any detail on current installations.

Chicago Lathe did tell me that the Patriot needed the JSS Scale: X-axis 26", Y-axis 18", & Z-axis 4"

Research seems to point to the Jenix brand for current installations.

I am looking for help in selecting the correct Make, Model, and Scale of DRO. Any assistance would be welcomed.

Update: I went with the Jenix Model 804 DRO.
Pro: bundle was very inclusive; a surprising number of brackets for different mounting scenarios; large count of allen head bolts/washers/nuts in multiple sizes; superb packaging; durable (dropped a glass scale on concrete floor w/o shattering the scale)
Con: does not accommodate axis readout coordination when moving from mill to lathe on my 3-in-1 ShopMaster; Jenix support did not have a work-around
