There's a few that get overall good reviews. I took a chance on my first Eart because it was 200 bucks on Amazon and had some impressive specs (ss frets, roasted maple neck, roasted mahogany(ish...probably) body. I ended up throwing locking tuners, new pickups and a Wilkinson trem on it, mostly cause I wanted black hardware.
After that I did a deep dive. NK guitars got rave reviews: I bought my first six string multi scale to begin with. Then I got one of their 7 string multiscale guitars. Then I took a chance on an MC Tang 7 string multiscale that I snagged for a song.
AliExpress was where I picked up those three. The thing to keep in mind: only buy from the official stores, even if it looks like someone else has the exact same thing for like 50 bucks less. Not worth the risk, even if they have good reviews it could be a triangulation scam. NK guitars, MC Tang, eart all have official stores in there.
They'll be having their 11/11 sale pretty soon here. If you're interested, I'd wait till then. That's when they tend to have the deepest discounts.
Threads on message boards asking for opinions are often crowded by folks who take a jingoistic view: there's strong anti-china sentiment out there. Some for legitimate reasons (human rights abuses, expansionist tendencies, etc) some for not-so-legitimate reasons (impotent anticommunist fervor, racism).
It looks to me like all the instruments I bought originated in Shenzen. I wouldn't be surprised if there's one factory there that is cranking these things out to semi-custom specs, as all the above brands seem to have similarities.
There are a few weirdnesses with these: the action and intonation is generally off from the factory. There may be some minor finish issues. The pickups are decent, but tend to need swaps for my tastes (except for MC Tang...theirs seem to be clones of the BKP aftermath).
But for the price...under half a kilo buck...yeah. A little setup ain't nuthin.
