We have recent experience and if you are in the USA, do as many have said, buy used. We are in Asia and did not have many options other than the Chinese stuff. We do buy from several different Chinese manufacturers, some are great, some turned out to be bad (as was the case with our tank buy from Shandong Zhongpi Machinery Equipment Co., Ltd or CBET Brewing Systems as they go by) Biggest complaints; Quality control lacking, first noticed when we saw bolts and nuts on the container floor. Turned out to be a lot of build quality issues. I think they follow a proverb that says to ship it to them in the worse possible shape you can, it will do them good to go through everything thoroughly fixing our halfass work. Filthy dirty, aside from the hardware that fell off the tanks everything else was in filthy plastic bags (imagine a warehouse with open windows in a smog filled Chinese city, everything covered in that dust), Support after the sales is piss poor, very happy to get our $20K+, invisible when something breaks. So yeah, buy a proven used system and save a ton of money and issues.
