Well, if you have a $100 to spend you could probably find a small (say 5"x1") vintage thuringian/escher and you're set having his recommendation. Or any of the alternatives should be good, after all afik he hones all the razors he sells, so he has most experience with honing these.

Finishing hone is the only thing you need for maintenance.

And put the same amount of electrical tape on the spine as used during honing (or a little more, but not less) otherwise your finisher is not going to be touching the edge but rather the opposite end of the bevel.
