I'll have to go with the Woodchuck also. I would recommend, however, getting the Bowl Pro rather than the PenPro. Both are wonderful tools, but if you are going to turn anything larger than pens, the PenPro may be a bit short. I made the decision after talking with Ken. He is the one that makes the tools. I use mostly the r4 cutter, but I do have the r2 also. I am saving up to buy the round one as it could come in handy from time to time. I use the Woodchuck from start to finish on most blanks, having to resort to the skew only rarely to form a special shape from time to time when the Chuck just wont fit.
