I finally lost the chuck key to a Makita 907d cordless drill.
The chuck has never been very good at holding bits, so rather
than buy a new key I'm thinking to get a new, keyless chuck.
 
Does anybody have a favorite, or suggestions to avoid? It's
a normal 3/8-24 right hand female thread, so that's easy. The
original chuck is Jacobs, are there better brands out there?

I have a bunch of chucks (mostly imports), but its surprising to hear
you didn't have like the Jacob's.  Usually genuine Jacob's chucks are
quite good.  I wonder if Makita licensed the name.

I was surprised also, Jacobs has always been the premier builder
of hand drill chucks, at least to my mind. It could have been
made under license.

I did notice the chuck seemed to lack lubrication, so for the moment
I've oiled it a little. Maybe that'll help. Still, the convenience
of not needing a key is very tempting. It's amazing it took me this
long to lose the original key...guess I didn't use it much.
