3/8" drill chuck replacement

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?

Thanks for reading,
