I like longer videos with more depth. At 12 minutes, this video is informative.

I think I have enough of an investment in my T7! It's worth it of course. :)
Ken,
I posted the T2 link for informational purposes only. I think the T2 is a well designed machine, for its intended users and purpose.
For a sharpener, a T4 or a T8 is a better match.
