I've been thinking about a 2 axis dro for my 12x36 lathe. I have PM machines, so I have been debating on an eBay special verses the PM 2 axis $399 kit. Is there an advantage to these mentioned above? I have a PM branded DRO on my mill, but I just don't have anything to compare it to. Its worked fine for me though. I guess the lathe version comes with all the mounting hardware? I wish PM had them preinstalled on the 1236's when I bought mine, I love the Mill with the 3 axis that came ready to go.
