One can never tell what the future holds, but for now, I am limited to a single bench. For this reason, I was hoping to stick with a bench lathe. I am anticipating that I will need a bench grinder, a small drill press, an arbor press, etc. that would be brought out as needed, and share the bench. I would feel comfortable for now moving a 200# lathe by myself, a few years from now, maybe not. If it ends up over 200#, I will have to get more creative in the use of space, but this is not a game stopper. If I have an occasional need for a bigger lathe, I do have some friends that might help out.
I appreciate all the comments. Right now, I am leaning towards a LMS lathe. I don't think I can afford the PM either in space or money.
