I have looked into some of the Chinese made ones and the all seem fairly similar, it would be nice for peace of mind buying a new one I will just have to see what is out in the market.
They are all indeed very similar at first glance, and often come out of the same factory.
There are difference though, they all seem to have some very odd design choices that need to be corrected by the retailer or you get a lathe with a weird limitation (like not accommodating a QCTP with out milling the compound slide). Often the lathe that seems to be cheaper is just a vanilla version schlepped off by the dealer, try to find a dealer the has ordered some changes.
I suggest making a list of features you must have, then a list of features you would like to have. Makes sure you consider size and weight. For example, my must have list was: 110v, under 600lbs, less than 100RPM, more than 1800RPM, min. 9" swing (>10 preferred), min 28" between centers (>32 preferred), reversible lead screw, left hand threading, Imperial lead screw, partial or full gear box (for easy feed speed changes), compound travel >= half the swing (many do not do this).
Once you have your list, make an Excel spreadsheet and start adding candidates. I put off making a spreadsheet and agonized for weeks making a decision, once I had a spreadsheet, it turned out there was really only three options and the decision of what to buy easily followed.
I looked long and hard to find a Weiss lathe, but they do not have a USA importer. You might want to consider one if you go with a new Chinese lathe, they are supposed to be a step up from Sieg, and are available in Europe.
