I read Mdls as models. He has a "floor" lathe and mill and wants to add bench top models to the arsenal.
I don't understand why. A big machine can do everything a small machine can. Maybe you just need to buy a smaller chuck. Mount it to an arbor and clamp the arbor with your main chuck for your few one-off parts.
If you still want benchtop models you need to answer one very important question right off the bat. Are you willing to completely tune up and rebuild asian machinery or do you want a quality product out of the box?
