I used to turn and owned various lathes from .5HP to electronic VS 2HP. For me, as long as you know what you need and know how to get it done, the machine (lathe in this case) is secondary. It does make your life easier but that mush in between your ears matter more.
I've seen some exceptionally talented people make wonderful turnings out of a drill press
. Can they do better with a better machine? Yes. Can I do better than these people with my 2 HP VS lathe...I wish but sadly no.
Some people count on the best tool so much but their skill/talent level usually doesn't really take advantage of it that much. If it works, it doesn't matter if it is a pedal powered lathe.
