From what I can tell, you as the owner need to know how to service the unit in your price range. If you have not looked into MakerGear, they are US company based in North East OH.
Their printers are work horse professional grade in your price range. When properly maintained you can count on there products to function for years without issue.
I don't have experience with any other printers other than my MakerGear which I purchased to have a highly accurate machine that would work for many years without issues.
That said, you still must perform regular maintenance and understand how the printer works. This is not set and forget technology at the price range you are looking in.
Good luck with your search.
