Advise on Replacable Cutter Chisels

[seabuggy]

Does anyone have an opinion on turning chisels with replacable cutters such as Easy Wood and Robert Sorby Turnmaster? The Turnmaster videos shows the turner working with the chisel on the rest much farther away from the wood than I would feel comfortable doing. I am venturing into other turning projects such as bowls, chess pieces, boxes, etc. I still enjoy making plugs, but I have so many, I will never live long enough to try each one even once. These chisels are advertised to do everthing and stay sharp for longer periods. I would welcome hearing your experiences with these tools.
