A Mill Lathe Combo Compared to an Individual Bench Top Mill and Lathe

A lot of people ask if they should get a mill/lathe combo or two individual stand alone machines.  There are lots of opinions but many of them don't come from a place of having experienced both.  I have been using a combo machine for over 10 years and now have two stand alone machines.  Because of that experience I decided to compare the two and give my opinion of these machines and which one might be better for you.
