I see the appeal of Inturn like 4rth axis if you are doing stuff like gears, pulleys, small intricate parts. Basically what i believe is worth having at home for a CNC lathe. Now if you want a CNC lathe for bigger parts that do not need indexing, i agree its not the best choice.

i am waiting for the day to come, but basically what i am going to do is fit to my mini lathe 700w servo motor, additional hydraulic disc brake from bycicle and thats it. Fit it in my machine. maybe change to bigger chuck.
