I think one common misconception is that you may think two machines are identical by their outward appearance, but each machine is built to the importer's specifications, tolerances and QC. So parts are not interchangeable. Also on warranty issues, I think it would be a lost cause if something didn't work or you needed parts at a later point. My biggest concern when buying a machine is long term parts supply and service, i.e. a company that has a local country parts and service center. I would also think of resale value, if you decide to upgrade change at a later point.
You can take a chance on smaller stuff like DRO's tooling etc., but at the machine level you are taking a bigger gamble. I did import a mill from a Canada distributor (there was one in the US at the time but much more expensive) years ago, there were some serious machine defects, some never got resolved and the distributor stopped carrying that brand a few years later. So I learned the hard way about replacement parts and service post sale. As others have mentioned about tariffs, it may be a different story now and although the direct cost to you may be attractive, you may get hit with significant tariff's after the matter of the fact. Also went through that experience and in addition to the import tariffs, the state wanted their sales tax.
The used machines like the G0709 Jim pointed to would be very attractive at this point. You still need to factor in delivery costs. The PM1236 is very attractive at the price point if that size fits your needs, the PM-1236T (Taiwanese) is also very close price wise and is a super lathe for the weekend warrior. The PM-1340GT, 1440E-LB, 1440GS would be on the short list, the price difference between Chinese and Taiwanese is now very close. I would seriously look at the 1340GT, I had one for many years and it is a wonderful machine. I would definitely opt for a 1340GT over a G0776 which price wise are about the same.
I know a number of other individuals that purchased machines (at reduced cost) thinking they were the same machine, many got burned when it came to getting anything covered under warranty and any post sales support/parts. You need to clearly do your homework, and know the machine you are getting as far as specs and build. I am not saying it can't be done, and the saving can be attractive, but I would not recommend it for this type/cost of machine. There are some import distributors, that essentially ship the machine from China to you and offer local support, Weiss comes to mind now that they have a US outlet. See example below, but there is limited experience. You may get a machines who's numbers on paper look good, but as I found out it may come with metric dials and lead screws as opposed to imperial or some mix of both. Had that on my last mill, making the dials useless.
