LeBlond built those machines with much care and precision, IMO. I have run more than one and never been disappointed. If the work envelope suits your purposes and the speeds don't bother you, then I believe it would be closer to what you should be looking for than the original Monarch in your post. If there is something wrong with it, parts may be a little harder to find than for some lathes, but that's the gamble you take with any older machine tool as a project. And, there is always resale if it turns out not to be what you really want or need. I'm sure you could get your money back, and possibly a small profit if you did nothing but a good cleanup and light refurbish. It's not going to profit you to get in depth as a rebuild, because the commercial market, where the money for machines really is, isn't all that interested these days in that type of lathe.
I would say if you can handle the transport yourself, you'd come out ok, but if you paid the premium riggers/movers.....not so much. You would have more in moving than in the machine.
