From all I've seen in other forums (and what is being repeated again here), some people love 'em and some people hate 'em.
It does seem as though there's a certain amount of "technique" involved that you have to learn, and until you get the hang of it, you'll never get a decently sharpened drill out of it.
When I was looking at them a while ago (I almost bought one, but got a very used SRD instead), their web site talked about being able to rent them at tool rental places. You might want to check around in your area and see if there is a rental place that does rent them, so you could try it out. Or send an e-mail to the Drill Doctor people and ask about that.
