Andrew this tool is similar in design to the David Ellsworth hollowing tools except the head can articulate a bit. The main difference is the handle that David uses is 28+ inches long and is held differently with the stabilizing hand behind your side, kind of like holding a pool cue. The tool will twist when you take too big of a cut, which is fine. It takes some getting used to but the design works. Most of the other hollowing tools you will find the cutting tip is in line with the shaft and reduces the twisting torque produced but the other tool design. This is not necessarily better just different. Then you get into cutting tip design and material...HSS, Cobalt and Carbide. I would really reccomend getting with a local club and take a go on as many as you can before purchasing. I have used about half of the different ones out there and own 4 different types not including the ones I've made. They all have their place. The captured bar or the articutaled bar tools(much different than the Sorby tool) are the easiest to use, but also the most expensive...even if you make them. Sorry if this wasn't a lot of help. Short answer, I'd keep looking.
