I have a couple of Scout 7NH and a Explorer 10NH made by Mag Flint Firestarter They are small and fit into a small kit well.
I also have a couple of small Mag Fire which are very good little starters.

Another I have in my Favorites is WSI but I havent used them.

I have a fire piston from Primal Connection which just arrived, and Wilderness Solutions also sell them.

You seem to have a lot of others already covered.
