Typically the collets run truer than the end mill holders.
I had a limited budget when I purchased my BOSS 9 so I purchased a pile of generic 1/2 inch end mill holders. Plus a few of the other common sizes. Then I purchased some small drill chucks with 1/2 inch straight shanks and some very small collet holders with 1/2 inch straight shanks. These were cut down in length as there was a lot of times where the 5 inch quill travel could not accomodate the drill chucks and other tooling. This gave me a great range of ways to hold tooling as most of my jobs were smaller in size. The only downside to the generic tooling was that it did not accept carbide end mills. I had to hone them out a few tenths.
