I make you right on all counts there too Peter and will admit to still using a home made jig very often for a quick gouge hone.
I am not condemning any of them they all do the job, but the price is extortionate for what you get with the named brands and totally unnecessary.
If you have money to burn then spend it by all means but it will still stand you in good stead to know how to hone properly without the aid of an appliance.
