I have the Super Nova2 and am very happy with it. I also like that accessories transfer from their older chucks to the new. It speaks of high quality support for what they make to me. One handed tightening is a must for me. the only thing that is a bug at all for me is that the tightening and loosening is backwards for me. Not that it is a big deal. strong chuck easy to change jaws as well as put on or take off the lathe.
I can't speak on the Barracuda other than I do not remember hearing complaints about it.
