The Park Tool DAG is a fine tool but is not a copy of Abbey. The only real copy derailleur hanger alignment tool (DHAT) is the EVT tool and the Shimano TL-RD11 but I don't know the history on that (I do know that EVT founder is in the Shimano Patent)
If I were going for a DHAT it would be Abbey unless I was using the tool a lot then I would go EVT but EVT is also super expensive. I like the Shimano TL-RD11 as well and would be cheaper than EVT but I want a more compact and lightweight tool for my usage.
