Yeah, I bought my 16x40 from Precision Matthews 10 years ago. Functionality is fine Fit and finish would never be confused with a currenr Euro, Japanese or Korean machine.
PM the company was fine AFAIAC, but it's basically a one-tech company. So the spare parts situation is even worse then the typical Chinese importer/distributor. The guy can be busy with work and slow to respond on occasion, On the plus side, he goes (10 years past tense) over every machine as it comes off the boat before shipping it on to the customer, and he specs above average mechanical components.
There is a difference in quality among import Chinese budget tools. PM seems to be competitive on that front.
So, you are ignoring digger, and he can be annoying, but there is a reason the class of machine you asked about is not to be discussed here on PM forums, I answered you because you rephrased the question into one about the seller. But for mill/drills, there are other net forums better suited for exchanging info.
