What most people do not realize is that with Chinese manufacturers, there are basically 3 types. The A Grade manufacturers produce some pretty good machines. Cowboy, Cobra , Sew Tech use the A grade manufacturer. I think all three of these machines are made in the same plant. Weaver has their 205 clone made in an A grade manufacturer. Nice machine.
Then you have the B grade manufacturer. They can make some decent machines or some bad ones. Probably depends on the day they are made. Then you have the C grade manufacturer which produce boat anchors!. Look good but sew and preform bad. The trick is knowing which manufacturer is an A grade. I with rare exception do not know which are the A grade manufacturer. Reputable dealers know. Buy from them!! Good dealers like Steve, Alexander, Bob, Ralph have found this out by trial , error and a lot of headaches. They know who to buy from. More importantly, what most people do not also realize is that these good dealers go thru each machine entirely and check all the screws and nuts to make everything is tight before they even sew it off. That is what you are paying for, a machine gone over.
Alan at Weaver told me years ago that every genuine Adler 205 that they got in would require 1-2 hours of checking all the setting and sewing off of the machine before it even got put on a stand. A genuine Adler!!! That was before the customer got it. Lesson here is unless you are qualified to work on a machine and know what to look for, buy it from the dealer. A lot less headaches in the long run and what is your time worth???
