I thought I'd share this one. I haven't purchased one myself, but the reviews from actual customers say it's top notch. A guy by the name of Craig Jackson came up with a replaceable carbide cutter and stuck it on the end of a shaft. This tool removes some serious wood, and quickly. He has since added to the line with the Ci2, it being a 3/8" size. On the bottom of the page is a video showing it in action. http://www.easywoodtools.com/index.htm He offers a straight edge cutter, and two with curved radius, 2" and 4".
I also see that Craft Supplies USA is selling it as well. http://www.woodturnerscatalog.com/store/New_Products___Easy_Rougher___easy_rougher?Args
