Matt (owner of Precision Matthews) is a good supplier, highly regarded, known for standing behind his products. Matt is also a member and commercial member on this site. That said, they are still Chinese or Taiwanese machines, built to a lower price point than something from, say, Europe. You WILL find things wrong with them, mostly stuff you can easily fix yourself, live with it like it is, or get help from the seller. When we take apart a Chinese machine, there are invariably plenty of signs of cutting corners to save time and money so they can sell them to you cheaper. You get what you pay for. Well, actually, you do not get MORE than you paid for. Not trying to put down Asian machines, lots of hobby machinists, including me, make good parts with them and are happy to have that decently usable equipment at that low price point. Remember that machinists do good work to their limitations, machines just do as they are told to their limitations.
