The unfortunate reality is that a durable, reliable, relatively fast filling compressor is no longer profitable to manufacture in the United States at a pice within reach of a hobbyist user. The manufacturing cost, liablilty exposure, and labor cost make an affordable compressor impractical to manufacture in the U.S. What most hobbyists don't consider is producing dry 4500 psi air places tremendous strain on the components of a cheap compressor.
Chinese import compressors dominate the low end of the price scale because they have cheap labor, have no liability exposure on exports, and the metallurgy is maginal at best. Quality control is hit or miss. For every user that gets a few months of trouble free usage there is another who doesn't. These compressors are disposable because of the difficulty of getting parts, factory repair labor is non-existent, and companies in China copy foreign brands with no regard for patent infringements. There are well known high end brand copycats made in China and sold on Aliexpress, Amazon and eBay.
Sadly, there is no cheap shortcut to buy a reliable, durable high pressure compressor. The best advice I've been given is to look for a used name brand compressor that has been serviced before resale.
