To answer the last point, I was going to buy a Wissota, but it can't be kept in my unheated garage. So it'd have to be indoors, and given that it is big, and messy, that is out of the question. So an automated machine is the only solution for me. And I like the fact that it can give a blade a few passes without me having to think in a minute or two.
Regarding Chris Kibui, I think you are unfair on him. I've watched Jeremy at Bauer behaving like a kid in a sweet shop asking no critical questions. Chris is I think no worse. His review of the Sparx and ProSharp Home machines is informative. And yes I do like Jeremy and Ken's videos, excellent stuff. But Chris is okay too, a bit wordy at times, but it's free tuition for some of us. Regarding sincerity, well it might be a case of patriotism perhaps, we tend to favour someone with our own accent/dialect. Just a thought.
