Chinese DACs

I just bought a DAC from a guy, who modded it, for 60 bucks and it sounds better than my newer NAD CD player.
I wish I knew which model I had. The guy who modded it said if you are buying a DAC for more than 150 bucks or more than two years old you are getting ripped off. Anybody else have good luck with Chinese DACs? Any you could recommend?
Here are the DACs that I have that are made in China that I find really enjoyable.

Grant Fidelity DAC-09. It can also be used as a tube buffer.

Jolida Glass FX Tube DAC with GE 5751 tubes.

96khz/24bit Hifimediy Sabre USB DAC ES9023 + Tenor TE7022
Kingrex out of Taiwan.
At $350 this is hard to beat.

I've not heard this model, but some of his other stuff, this has all the current bells & whistles, proven technology and a great price.
I also had the hifimediy sabre dac and was impressed
Dac destroyer (not chinese but cheap) have pretty decent performance as well.
Mhdt Labs, Taiwan
The MHDT is a very good dac, and you can't beat the used price they are selling for.
The MHDT havana is very popular, but pricey. I'm not sure if Op is asking for budget dacs only.
Eastern Electric MiniMax, hands down the best under 1k new, opamp rolling is another great feature.
