For my chamber brush I use a dewey 9" loop pistol rod that I picked up from brownells for $6.

The loop at the end gives you plenty of leverage for twisting the chamber brush. Cheap and easy.
I find it's much more cost effective to build your own cleaning kit with exactly what you'll use, as most of the ones you see available for sale either have junky components, or try to make you feel like you're getting "value" by including all kinds of worthless stuff. For me, if I was starting from scratch, the bare minimum I would get is:
Jag
Bore brush
Chamber brush
9" pistol loop rod for chamber brush
Dewey coated rod
Q-tips
Patches
All of the above is just over $50 at brownells, and $30 of that is the dewey rod. You can substitute for something cheaper, but make sure it's one piece and coated or brass.
