New Chinese compressors

I noticed on eBay there are some compressors that appear to be copies of the daystate units . Selling in the $2500 price range DAVV is the name showing. 

Anyone know anything about these units. Have they been around? I wasn’t aware of them.

One if the things I’ve noticed is there seems to be almost no information on line about compressors. Trying to research and get prices is difficult. Unless you live in Fl. maybe even then 
 
They are Chinese copies of the Coltri MCH6. They've been around several years. At only 20% less than the real MCH6's, I don't see the value, but that's my opinion. I'm also starting to see Chinese copies of the Bauer Jr. II priced in the $2500 to $3000 range. I'd rather buy a genuine "used" Bauer for that price than a new Chinese copy. I'd be questioning service availability, parts availability, and the metallurgy and tolerances of the copycat compressors. A cubic zirconium at 80% of the cost of a diamond does not make sense to me. JMHO.
 
The devil is in the details. We tend to assume the Chinese stuff is inferior and it may well be ( or not). 

I live in central Pa and I don’t know where you’d even go to buy a Bauer compressor new let alone get service on a used one 

I’ve got a 110 daystate and service is essential shipping to AOA. Not exactly a give me. It’s pretty much a buy online regardless. 

The down side on this air gun stuff is service
