switching Jacobs 2 drill chuck to ER collet holder

I've got a HF spindle with a male J2 output shaft.
The spindle came with a Jacobs style drill chuck with a key.

I'd like to upgrade to a proper collet holder, ER?

So, Looks like I'm looking for a ER collet chuck with a female J2 taper.

Any help much appreciated!
