I have the PSI Barracuda 2 and the PSI utility chuck. I bought them when I was turning on my ShopSmith with a 1x8 adaptor, and they moved to my Jet 1220. I purchased the PSI chucks since they came with a great selection of jaws, though I had to add the #2 dovetail jaws for $20. I have turned many small bowls on my 1220 and they worked very well. The utility chuck tightens with two bars, but if you lock the spindle, you can do it with one. The jaws are compatible between the two. I usually use the #2 dovetail and the PSI version of Cole Jaws. These chucks do not have a locking screw, but since the 1220 does not reverse it was not a big deal. All in all, I feel I got a lot of bang for my buck. They hold great and no noticeable runout.
I also have a Jet 1642. It has a 1 1/4x8 spindle so my PSI chucks would not fit. I decided on the Super Nova2 chucks because of the jaws available. I have no complaints. I have done some larger bowls and platters and the Nova chucks perform great.
I took a bowl turning class, and someone asked the instructor which brand chuck he liked. He said he has used just about every brand out there and they all basically do what they are supposed to. He had no strong feelings. He definitely had strong feelings about chisels other accessories, so I am pretty sure he was being truthful.
