Do a forum search here on 5C, the topic comes up a lot. Clough42 also did a recent review of his Asian import. Some have been satisfied, others not so. Also depends on what you are trying to achieve & condition of your machine. Accusize imports/distributes Chinese tooling but whether they are selective to various Chinese manufacturers I cant say. It may or may mot be any better than others, its difficult to compare. The consensus seems to be that their return policy seems to be OK, shipping back at your expense wouldn't be horrible, they are in Canada, so there's that.
FWIW my direct mount D1-4 new Bison 5C ~15 years ago had ~0.0015" runout. I sold it when a good deal presented on a Set-Tru model which can be dialed in. But Bison prices have gone through the roof. There are import versions of Set-Tru now which might be worth considering, but no personal experience. Gator line is dimensionally the same as Bison but ~80% quality IMO based on scroll chucks I have & price wise are more than regular Chinese, not as commonly distributed
strangely, better Bison prices than in Kanuckistan all fees & expenses in
based on my R8 collet experience. I would consider these guys for collets (mentioning this to others, your Lyndex are top shelf keepers)
