I don't have any experience with the Woodchuck, but it sounds like people really like it.
I did buy the Easy Wood Tools about 2 weeks ago. I bought:
Ci2m Mini Rougher
and
Ci3m Mini Finisher
I watched the videos online at their website. They show using the Mini Rougher in a way that you plunge it strait into the turning material. I had problems using it that way with burls, and broke 2 of them. Also, because the cutter is flat across, the edges can catch on material if you try to run the tool left/right along the the tool rest. I see some of their full size tools offer a cutter with a slight arc, so maybe I'd prefer that style.
I do really like the Mini Finisher. It's makes a very smooth cut, and I've used it on about 10 pens so far, and haven't had to swivel the cutter around yet for a fresh edge. Very happy with that one.
