I have had my 9x20 for several years now and I can't complain. It dose everything a big lathe can do but in smaller cuts. Only added labor is that of changing gears for cutting threads, o problem and changing belt position for changing speeds, no problem. I have don most of my work at 130 rpm and it works well. Maintenance is the same as any other lathe.accuracy is excellent and up to you to perfect you measurements. I make gun parts on my lathe and I am happy. You get a lot for the $$ you pay, Now I am very happy.
