Just checked and verified, you need to transport it up stairs. So I think fair price for the lathe is closer to $1500 maybe less. One would have to inspect the stairs. But I assume one would need to pay for any major damage caused. Given lathe size I expect it would need to be de-assembled, and moved piece by piece, i.e. lathe bed, headstock etc. Probably two days or so to disassemble it, at at least 3, to 4 days to re-assemble it. And you better know how to re-assemble it properly. So with move we are talking about a week++ worth of work. This is a project for someone who does not work.
Same for the mill, but I feel it would be easier to put together - still probably a week as well.
I would talk to Dabbler. He has experience in these things. It took him like a month to move multiple machines from basement. They used things like windows if I remember correctly.
Moving company quotes started at $10,000 and went up from there - again Dabbler is the source.
One would have to scope the stairs to have better idea. Current prices are for machines that can be easily had - i.e. like in a garage or ground floor.
