Argo Navis vs. Sky Commander

I hope this doesn't bring back the discussion of "greying" (or is it "graying"?). It may be a gray area. Anyhow, has anyone used both Sky Commander and Argo Navis? It seems Argo Navis would be the winner, but it costs almost twice as much for the whole package. So my quesiton is what are you getting for that much more? Which is easier to use? Also, for people who need reading glasses like me, can one be read more easily than the other?

Hi Paul.
I have both and use both.
The Argo Navis has more options such as tours, spiral search, TPAS and the ability to set the magnitude for objects in the search. It is a great unit and TPAS allows you to map the errors in your mount and make up for them.
The Sky Commander is simple and small as well as lightweight. It has a lot of objects and catalogs and works well.
There is no real difference as far as accuracy is concerned, except for the TPAS.
I like the Argo a lot, but I keep the Sky Commander too because it is small and works well with my 10" DOB.
The Argo has a good illumination, but I have to use reading glasses to read either one of the DSCs.
Which is best, I would vote for the Argo Navis.
