I dont know about other chinese ballscrews but I have bought and fitted dozens from Chai at linearmotionbearings and they are very good considering the money. . . More than good enough for Diy.
I have some of chai's screws on my big machine and they are just starting to show signs of wear after 3 years of very very hard use cutting mostly Ali plate and in the worst possible conditions due to the fact they are uncovered and partly in the firing line.!! . . It's one of them " I'll do it later" jobs that after 3yrs still aint got done.!!! . . . .

BIG TIP . .DONT Start the bloody thing up untill you've done every thing you planned else they'll never get done.!! . . . So much fun you'll never want the down time.
