Did not like using my ML7 with the Rodney milling attachment, because the ML7 is good lathe, but not rigid enough for anything but very light cuts when milling. Have used a Warco Economy Mill/Drill for about 20 years now.
Too early to have a dovetail column, so have to use a Laser aimed at a pencil line on the far end of the shop to realign the head when moved up or down, part way through a job.
If the budget will run to it, use a lathe for turning (you can use a vertical Slide for light milling over a short distance) and a Milling machine for milling.
When choosing your lathe, (or any other machine for that matter) think of what you might need in the future. As someone said to me "You can do small work on a big lathe, but not the other way round"
I would rather change speeds with belts or gears than electronic controls, although my 12" swing lathe has a VFD. The many reports of boards failing on some of the variable speed mini lathes do worry me.
If you are not a member, join a M E Club, and seek advice and help there. You may get conflicting advice, but it will come from wider experiences, so sift it and then make your choice.
