I have a D1-6. These things any good?
I've heard mixed reviews.

They are great! I ended up grabbing an L1 version of it and a set of the collets, and they are an incredibly accurate way to hold material. I end up using it rarely, but its perfect as a collet chuck.
 
I've been considering an ER40 set-up. I already have the ER set. I would need the chuck and backing plate (D1-6)
I can't remember who it was on this forum but they had some issues with these.
I have seen plenty of guys on Youtube using the Jacobs with high precision.
I just don't know how often I would need it.
Being a hobby guy and all.

I'm also a hobby guy. Where I use it most is when I have to hold a section that is threaded. You obviously cannot hold threaded material in a 3/4 jaw without destroying it (or using a soft shim, that hopefully won't slip!), so the collet fixture works great!
 
Erich,
That is a very good point.
How about repeat-ability? You would never remove a part from a 3 jaw until it was finished.
What about the Jacobs?

Mine is dead on, but it depends on the condition of the collets I think. Mine keeps center to ~3 tenths as far as I can tell.
