When making a decision as to whether to buy used USA made or imported machines. I considered the possibility of buying a used machine that had unknown defects where my time would be consumed with trying to make things right vs. buying a new import machine with documented shortcomings which could be corrected.
With the exception of an Atlas Craftsman 6x18 lathe that I bought in 1970, all my machines have been new Asian machines. I have done some modifications on all of them but have had no serious concerns with any of them. In an old used machine, replacement of defective parts can be a major issue, With new machines, parts are usually available. When you buy a used machine, it is usually "as is" and any hidden problems become your responsibility. With a new machine from a reputable dealer, you have your warranty and customer service to make thing right.
