Does anyone have either of these linear guides on their machines? How do they compare in terms of quality and performance compared to Hiwin?
I saw from a youtube video that PMI-AMT are interchangeable with THK anyone can confirm that?
CPC(Chieftek) is almost unheard of till I saw their youtube video.

I wanted to install Hiwin roller linear guides (RG series) for my machine but the sales from my local Hiwin country office informed me there is a current leadtime of 150-180days!
There are some Hiwin RG guides found on Aliexpress but I'm reluctant to buy from them due to the number of Hiwin knock-offs sold on that site.
