Evenin' Matt. I use 2 Supernova chucks in my work and am more than happy with their performance.
There are more expensive chucks around, as there is also a few cheaper models. The Nova is pretty much middle of the road as far as price goes.
When looking for a chuck I always say that, you should be able to move the chuck to another lathe if you ever upgrade. Just need to change the Nova insert. It should be a reasonably popular chuck so will be around for a few years, and that there is a fair selection of different jaw sets for it. The Nova has met all that criteria for me.
