I have a Chinese 5x10 router of 2010 vintage that I bought used. There is a little bit of support for them, although that varies by company, but I have seen factory techs over here to help setup machines so that is probably an option too but pricey compared to the machines. Research the brands over on CNCzone as some do have zero support and some are better.
My other shop, run by my brother, bought direct from Omnicnc in china, 5x10 with ATC and syntec control which was same as the used machine had.....they run very similarly and in general are simple machines mechanically which is a plus. They are also basically a method of dumping steel for the chinese so their weight is in the "heavy iron" class of machines which can itself sometimes be helpful for vibration dampening.
As said above, buying one direct is best done by someone who could build one themselves or retrofit it if needed. Shipping costs might be an issue right now too.
In general, a US reseller or US manufacture is a better choice for many (US manufacture will not be as heavy as the Chinese built but can be competitive price wise with resellers). If I went that route, I would look at Techno CNC as they pivoted to Chinese supplied CNCs but have been selling machines since the 80s (Techno Isel back then) and seem to be doing well and I don't expect them to shut the doors any time soon, as well as Cammaster, shopsabre, CNT motion, and maybe a few others. AXYZ, Multicam are bigger names, but you are mostly paying more for a good set of options and broader tech support through a dealer network.
